I have the opportunity of buying an Original condition Goldring Lenco GL75 and would like recommendations for upgrading this turntable to get the best out of this idler.:)

If anyone can suggest an upgrade path I would appreciate it.

Whilst I am sure there are those here with the knowledge, I would suggest an extended read of the attached. There seems to be every possible variation of upgrade available there. Alternatively, just send it to me as it will be a whole lot of trouble. I am still looking for a suitable model after rebuilding my Dual and I've decided that idle(r) is where it's at.

Nice turntable the L75. Go ahead and get it if you can.

The sky's the limit really when it comes to L75 mods. As Gordon says, LencoHeaven is your place, although there are many members here who have radically modified units.

If you get it, post in this section and I'm sure you'll be deluged with replies.

had one myself and they are decent without mods. i have an arm in good condition lying somewhere if you decide to stay with the original and need one or you gordon. i am unlikely to need it now

Hi Gordon,
I will consider my options and cost/work involved and if I conclude its too much bother I will put you in touch with the guy selling. I have plugged it in to my system and given it a spin and all seems to be working fine, even with its original Shure cartridge. Sounded OK even though it had not been used in the last 25 years:eek:

Jim they are excellent turntables and a very simple design compared to my Garrad 401 I have heard several of them and have worked on one at my home so I'm sure you will not be disappointed when you get it fettled the way you want it.
I would recommend you rewire it all with a nice flexible mains lead then clean and lubricate all the linkages and bearings.
The top plate can be a bit vibrant so it helps to fix this down to a nice solid wood plinth
All the ones I have heard haven't used the original arm so I cant comment on how good that is?, Steves lenco sounds good with a Jelco arm and I think the Rega and Linn arms would be OK but you will have to fill the old arm mounting hole and make an armboard
I think the best sounding one I heard was a Slate plinth PTP mounting plate and an Ittok arm belonging to Paul3
Like others have said Lenco heaven is the place to go

Thanks for the advice Alan. I think I will probably buy the turntable from my mate if I can get it for a good price and use it as a project. I had a quick look at Lenco Heaven and can see there are many routes to go down with this turntable. I think I will initially just rewire, clean and replace worn out parts and try and get it working as good as possible in its original condition. Then move onto more ambitious upgrading later.:eyebrows:

Now come on Andre,

I got this when I modified the Dual. They are not great works of art and there are obviously plenty about so we are hardly likely to rid the world of the irreplaceable. Yes, they are good engineering but times change and if someone owns something and feels they get improvements from their changes, I just don't see the problem. If they do become rare, presumably the remaining owners will have something that could be considered an investment. But then they probably wouldn't use them for fear of reducing their value. Better to keep them going, doing what they were designed for, even if altered.

My Dual sounds better for the changes and I enjoy it more now.

I have now bought this GL75 for 50 after some tough negotiation:) Sorry the pics are poor, I will put some better ones on later and as I work through the project.

Initially I am just going to give it a good clean, replace some of the wiring and the captive RCA lead which is in very poor condition. Then work on the main bearing and regrease. I will try to get the best out of it in stock condition including the arm but may replace this.

26-01-2015, 13:05
I'd looks as though its in jolly good nick, so 50 was a steal! You'd pay three or four times that on eBay. Doesn't even seem to be suffering from a droopy counterweight, which is amazing! The original arm is capable of far better performance than mostb people give it credit for, but one thing you have to check is the condition of the horizontal bearings. These consist of a metal knife-edge resting in v-shaped rubber blocks which distort and deteriorate over the years, severely affecting the arm's performance. There are replacements available made from better materials than were available in 1970, and they aren't hugely expensive. Check out Lenco Heaven or EBay.

I'd go with your plan to clean, lube and rewire, but I think rewiring the arm as well would be a good idea. Once its up and running, junk the clunky old Shure and get something with a bit more finesse, then research plinths. Ideally slate IMHO, but anything good and solid that's shaped to support the underside of the top plate properly will transform a good solid performer into a world beater.

It's an early ish one as it still has the black control knobs, later ones had brush aluminium inserts. However yours will have 'V' Blocks.. There should be a date stamped on a label under the platter.

Were the early ones unsprung as I think this one is definitely sprung?

When I get it back to my house I will get some codes off it to help identify which year it was manufactured etc.

The Early 60's ones were Lenco 'L75' then came the Goldring/Lenco 'GL75'.. Yours is an early 'GL75' because of the black knobs as mentioned & what looks like it's made in Switzerland & not Italy.

Ribs or not, the original mat is a goodie with this deck I think.

Earlier GL75's sat on four grommets (one in each corner) and were held in place with two self tapping screws on plinth blocks in a plinth that had a sprung base and a lid with stay that Linn used in the first few years (the metal trim was the other way round, that's all). Later decks towards the end of its life (and around the time of the GL78 being introduced IIRC), the plinths became solid and the deck was mounted on flat, concentric springs, the two mountings not compatible. My GL78 won't mount in the early sprung 'Goldring' plinth I have without some butchery for example!

The original Shure cartridge even plays a few tunes without disgracing itself. Anyone got good ideas for a replacement that works well with the original arm?

Denon DL-110 is not too demanding, sounds nice and should work OK in the L75 arm, long as it's all done up tight.

The difference between my heavily modified Lenco and my VPI is substantial. Not really sure if its better, but it sure is different.

I reckon a well sorted L75 with a good arm will compete with just about any other TT at almost any price including VPIs.

I picked an early l75 up here in CH when I first moved back - CHF 25 :). I checked/serviced it, whacked on a DL110 and compared it to my LP12. It was crap in comparison - it was still in original plinth, but even so, it was rubbish. I think the stock arm is crap - I had to make new vblocks just to get undistorted sound, but it was still not good. I now have an LVX & As-212 to try instead, when I get time.

Have you released the screw halfway down the bronze bearing. It can hold the platter spindle. If it's just a gummed up bearing holding it, try a squirt of WD40 or silicone oil and let it soak in for half an hour.

If you're planning to lubricate the main bearing, use EP80/90 transmission oil. It works fine on the Lenco bronze bearing.

Also. Clean the tapered motor spindle, the rubber edge of the idle wheel that bears upon it and the underside of the platter with meths. Use a tiny dab of silicone oil on the idler wheel bearing and on the motor bearings. It'll keep the grease in the motor bearings from drying. Just use a drop on the end of a cocktail stick. That's enough.

Cheers For the advice Geoff. I am not planning on doing a full strip down service myself but will degrease and oil the bits you have suggested just to get it up and running.

Will get Dominic at NWA to give it a full going over.

I would like to keep the Lenco on original condition of possible and try to get best out of it with original arm.

Why not?

They are very simple and so easy to work on. If you want advice just ask me. Or anybody else here who has experience of them.

The arm is easy to sort too.

There's loads of stuff on LencoHeaven too: http://www.lencoheaven.net/

There really is nothing on these that you can't do yourself with a bit of basic research, simple tools and patience. They are actually quite rewarding to tinker with and easy to get familiar with.

I haven't played with one for twenty years. But could probably do it with my eyes closed! :D

You don't need to release the bearing housing screw to release the platter if you have 3 hands - two to slightly raise the platter, a 3rd to give a gentle tap on spindle with a piece of wood and the platter will come free.

And I completely agree with above - they are simple to work on, great engineering. Strip, clean, re-lubricate bearing, idler & motor (reset motor end float) and you have a great motor unit. Mine sounds great with an AS-212 bolted straight into stock chassis (original arm really is rubbish IMO - even with new vblocks and fixing the end stub in place).

Yes. I've heard this before and although it may apply to some Lenco 75s, I've had occasions where the screw does prevent the platter spindle from releasing on the twenty or more of these I've owned.

It's a good idea to rake the screw out anyway when relubing, as the oil pressure in the bearing can blow the nylon end cup off otherwise.

shane
25-09-2015, 09:19
The platter is a taper fit onto the spindle, and the spindle is locked into the bearing housing with the screw mentioned above. Best to take the platter off the spindle first by lifting the platter and gently tapping the top of the spindle with a piece of wood. As mentioned, this is a two man job, one to lift and one to tap. Once that's done, you can do everything you need to do to the motor, idler and wiring. You only need to remove the spindle when you get to cleaning and lubricating the bearing. Then simply undo the screw and withdraw the spindle from the bearing housing. I can't think of a circumstance where you'd want to remove the platter with the spindle still attached.

Although I am intending to keep the existing arm there seems to be many folk who don't rate it much. I will listen and evaluate.

However can anyone recommend tonearms they have tried with the Lenco which do a better job.

I believe all Linn arm have similar mounting geometry to the 75/78 arm. I have a Linn LV-V that I intend to mount in one. The LV-V is good with MC cartridges.

The platter is a taper fit onto the spindle, and the spindle is locked into the bearing housing with the screw mentioned above. Best to take the platter off the spindle first by lifting the platter and gently tapping the top of the spindle with a piece of wood. As mentioned, this is a two man job, one to lift and one to tap. Once that's done, you can do everything you need to do to the motor, idler and wiring. You only need to remove the spindle when you get to cleaning and lubricating the bearing. Then simply undo the screw and withdraw the spindle from the bearing housing. I can't think of a circumstance where you'd want to remove the platter with the spindle still attached.

Because it's easy.

As above - any Linn fit arm - use VE database to check which arms this covers. Only item to watch is how low you can mount the arm - the platter is pretty low on the Lenco, so you need to be able to sink the arm down a fair down into it's collar to get VTA right. Ortofon AS-212 arm collar fits into the stock top plate hole with a little bit of play, the stock Linn collar would need a little bit of filing of stock top plate hole...but I think you can also use the stock Lenco arm collar instead (with an old film case over the Linn arm base to make it a good fit into Lenco collar).

...try saying that quickly after a tube of wine gums :eyebrows:

I have just taken the bearing apart on my GL75 and found....a ball less bearing :eek: No wonder I was getting some wow, the spindle was resting directly on the plastic bearing plate.

I had to search for a replacement ball, it's supposed to be a 5 mm ball but I had to fit a 4.7 mm as that's all I could find.
Seems to work very well though,

Actually - that is a concern of removing the screw and lifting platter/spindle out together - be careful you do not loose the ball bearing - the oil in my bearing had turned to a gunky sticky mess and lifting out spindle when I stripped it, the ball bearing came with it...hidden inside a spludge of gunk :)

Ok AT95E now fitted to Lenco. Easy job with the Conrad Hoffman protractor- bang on alignment! Very quiet running and smooth,silent operation apart from the clunk of the cue lever dropping and a very squeaky brake! Tracking is perfect although the headshell is a bit agricultural. I had to pack out one of the screws to get better azimuth. Not sure how to adjust VTA but seems fine. Running the At95e at 2g.

Tonearm seems OK although having to run anti -skate at maximum? Looking from the side the back of the arm looks to lift slightly after the join on the pivot, is this normal?

Very impressed with At95e although needs to run in a bit more yet.

Comparing it to my VPI is not really fair as this has a 2M Black but I am very surprised it does a very fair job indeed. Thing that struck me the most, and I agree with you here Marco, is the drive. I can hear the benefits of an idler. Difficult to put into words but the constant unwavering propulsion of the drive gives the sound a more solid flow. Slightly more coherent than a belter.

The Lenco is not producing the soundstage, dynamics and bass I get from the VPI/2M Black but the detail and musicality is up there, very listenable.

I wonder how much better this TT could sound after a good service and an even better cartridge?:)

A well sorted L75/78 can compete with any turntable. The arm can't though. It does an OK job up to a point, but its limits are easily reached.

I had a G88 and a G99 in sturdy plinths, both fitted with decent arms and they sounded superb by any standards. The L75 can be made to sound just as good.

James your example looks in better fettle than the one I have :eyebrows:

However I have to agree with your (and others) opinion that a good idler drive TT imparts a 'drive' or put another way, a solid underpinning to the delivery of the music.
We have been listening to some good vinyl since 're-balling' the bearing and the sound is intoxicating.

As an indication of the drive that the 75 has got, it transpires that without the ball in the bearing there must have been quite a lot of drag as I have had to adjust the speed selector positions downwards by some margin.
It's no surprise now that there was some wow apparent, in fact the big surprise is that there wasn't a lot more :scratch:

Fortunately when I bought the TT it came with some spares, including a spare headshell, as the one fitted had taken a knock and was bent downwards. On trying to straighten it the end connector became loose so had to be removed from the shell in order to straighten every thing up. Super glue came to the rescue when re-assembling.

So with two headshells I fitted one with an MC and the other with an MM cartridge.

http://i601.photobucket.com/albums/tt97/Paramotorpilot/P1050130.jpg

It turns out that there is only a 0.5 gram difference in weight so I can dial that in on changeover on the tracking weight adjustment :)
Needless to say the MC sounds better with a more cohesive and fuller sound.

http://i601.photobucket.com/albums/tt97/Paramotorpilot/P1050131.jpg

The counter weight and tracking weight arm are not quite straight, although rather more so than when originally picked up, but I'm right pleased with it.

:cool:

Hi Alan, funny we both ended up with one of these.:) Goes well with valve amplification too.:lol: I am extremely impressed with how mine is sounding, you must pop in when your over for christmas. I am still scratching my head.:scratch:

Did you read that very long article I posted earlier, went on a bit but there were some interesting observations regarding the Lenco idler drive.

Which MC cartridge are you using. I may scout around for another headshell to run one but then I would need a MC phono stage:) Not sure how compatible the arm is with top MC cartridges?

Regarding your bent arm, I have the same with mine at the back where the counterweight sits. Consulting Lencoheaven suggests this is not a major issue and is not detrimental to SQ. I am going to try and get the best out of the OE arm as again Lencoheaven suggests many folk swapped to an alternative just because they did not like the look of it and did not compare it before junking it for an alternative.

The idler mechanism certainly does give the music an incredibly stable drive and underpins the music in a very positive way. Quite addictive,not sure if I can go back to my VPI! What would it sound like with a 2M black up front?:)

There is little choice.

Sony had their own version on the PS5011 (I believe it was), which was a rebadged Lenco.

There's the L78 perforated headshell.


And on 'Lenco Heaven' there's a guy selling these (trade) for the L70, which may be suitable.

Which arms work best with the Lenco GL75. I am open to any considerations but would like VTA adjustment.

Jason P
15-02-2016, 16:17
Anything Linn based (geometry wise) should drop right in, so a Jelco or similar would be a good match - but as far as VTA adjustment goes I'm not sure. Rega based arms need new mounting points, but you could then go for an Audiomods with the micrometer VTA adjustment. Most people with Lencos turn the top plate round 90deg in a new plinth to accommodate new arms (I'm not a fan of that look TBH) or blank off the existing mounting hole and fabricate a new one, but we're into major mod territory there...

However re-plinting gives you a whole plethora of options arm-wise, so it might be worth considering - mine works very well with a non-micrometer Audiomods, but the world really is your oyster at that point! Re-plinthing will also yield sonic benefits too if done right. There's a load of info on Lenco Heaven, lots of templates too.

If an LVX drops straight in I may have to try a GL75 again. I've got one (maybe 2) of these decks but the only time I ever tried one, many years ago, was with a unipivot arm and it sounded bloody awful! Loads of rumble and the sonic sophistication of a music centre :eek: I have heard modded and sorted examples with other arms sound very good more recently though so I don't know if it's just a case of a unipivot being an awful match to these decks or if it is just knackered....

Linn arms do have the correct geometry for use on the L75 Jez. You merely need to drill the three mounting bolt holes.

I have a few Lenco turntables (in various states of assembly) and have purchased an LV-V to use on one. The LV-V being the only Linn arm with a universal/SME fit removable headshell and highish mass, making it suitable for use with most MCs (and Deccas). The bearings and general build quality are decent.

You previous L75 experience makes me think it must have had mechanical problems. Good examples of these turntables are very quiet and rumble free normally. Maybe somebody lost the ball from the main bearing that bears upon the thrust pad. I've seen that and it wrecks the quiet running.

I'm sorry, I was being facetious - I really don't like the stock arm (at least, with DIY modified metal screw vblock replacements), it is complete rubbish.

If the cartridge isn't too lightly damped, nowt wrong with the L75 arm once the V blocks are replaced. I don't know how easy it would be to replace the internal wires though, of which some are internally corroded (GL75 deck plates rust too if badly stored). The Thorens TP16 arm can have the shell socket removed by drawing out the fixing pin and the L75 arm looks similar, but I don't know if this could be done. If so, an Audio Origami foam fill and maybe some layers of cotton thread on the springy counterweight beam to slightly stiffen and support it may just be enough, with one of these Thakker shells, to prevent use of the now almost inevitably knackered LVX or Basik Plus arms. I wonder if current Lenco shells (the one from their DJ deck) would fit?

I still maintain that the L75 horizontal bearing/bias assembly is a good one with gravity loaded low friction ball races, which usually spin well - if they don't they're either badly adjusted or abused ime. If only the existing arm beam can be used to advantage, it could be an amazing deck today, as the original one sounded with stock mat, a fresh exit cable and K9 fitted - absolutely annihilated an Axis with Basik Plus/K9 in direct comparison.

Thanks Geoff. I have a Audio Technica AT-1005 Mk2 on my main deck at the moment and suspect it may well go straight on the GL75.... It just mounts into a round hole like a Rega RB300 and the stem looks a tad smaller diameter than a Rega. I don't know how standardised the mounting of various AT arms was over the years but maybe someone can confirm that will go straight on to a GL75 and save me from needing to drag things out of cupboards and measure them etc....

15-02-2016, 19:59
I am getting great results from the stock GL75. It is a very quiet runner and sounds probably better than my VPI!

I was just wondering what arms folk recommended for use with the Lenco other than the stock unit which to be honest although it looks a tad basic and a bit ugly it seems to perform well.

I have some Desmond V blocks to pop in so if they improve it further it will be a very accomplished TT. I heard it recently with Firebottles Ortofon Salsa MC and it blew away anything I have heard through my system by quite a margin do I am seeking out MC options for the Lenco which will push it too it's full potential.

Don't really want to go down the modifying route although I can see the fun and potential, rather leave this expense and time for a 401 sometime in the future.

I have seen photos of the AT-1005 II fitted to the L75, but I'm not sure whether any alterations were needed to accomodate it. I'd think it straightforward enough though. You might even be able to use the fitted Lenco armrest if it's clear of the sliding downforce weight.

Having just done a scout about on the net. I've found the length of the AT-1005 II quoted as 228mm. I suspect that may not be the stem centre to TT spindle centre dimension though. The Linn is 211mm stem centre to TT spindle centre and the Lenco arm 210mm.

This one: http://theartofsound.net/forum/showthread.php?43259-Fs-Audio-Technica-AT32E-mc-cartridge

It is of medium compliance, as opposed to low compliance like most MCs. The Lenco arm is at the upper end of what I'd suggest is medium mass and I reckon the two items would work OK together.

The cartridge is a low output type and would need an appropriate phono stage or a decent SUT.

Ok so rather than go down the MC route I have decided to fit my Shure M55e / Jico SAS cartridge to the Lenco.

Compliance not an issue and as it came originally with a Shure M44-7 this is certainly a good match to the stock arm. Used the Lofgren A cartridge alignment template which is certainly very handy for dialling in overhang. Tracking force 1.5g. Set the platter speed up bang on with a Dr Feickert Analogue test disc tone and iPhone app - very nifty and simple system.

First impression, this is a perfect match for the Lenco GL75 it sounds right from the outset. Obviously with the Jico SAS it has turbo charged the performance.

Only got to spin a few discs last night so need to get through some more stuff before I can evaluate performance but listening to some jazz it sounded very good indeed.

Decided to strip the platter bearing and clean/ oil as i was changing the V blocks to Desmo V blocks. Err the Spindle has a touch of surface corrosion and when I disassembled the bearing it was bone dry!:eek: This maybe why I heard a bit of noise from the deck.

Took the arm off and popped out the V blocks - to be honest they were not in bad condition but as I had new Desmo blocks I decided to pop these in anyway.

Letting the bearing run in a bit before I try the upgraded GL75:)

Cheers Marco. Funnily I was just discussing this very question and it is quite a different presentation.

The M55e / Jico is a marriage made in heaven for the Lenco and does sound very good indeed with great balls, drive and detail. I would say the Lenco does better bass and has rock solid timing and is now very transparent in my system with the new V blocks allowing the cartridge to be set up to its optimum? Certainly very musical.

However we have done a back to back with the VPI / Denon 301 using the same recordings and there is quite a difference.
The VPI/ Denon sounds even more detailed, which I found a bit of a shock! The Denon also floats all the instruments in a more transparent liquid way. There is even more natural realism in the presentation and an ethereal body to the sound which has a magical addictive quality. The VPI / Denon also has a bit more air and lushness to the presentation. Certainly the way it deals with jazz instruments and in particular sax and trumpets, the Denon is sooo smooth and full. The M55e/Jico is a tad grainy and harsh in comparison. Cymbals shimmer without any glare with the Denon but the Jico although detailed doesn't present them with quite the same natural sound.

The Lenco certainly has more grunge in the bottom and I expect being an idler it conveys the bass in a more convincing way but in a sheer musical way, being there with the music and performers, I think the VPI / Denon pips it.

Jimbo
17-04-2016, 10:10
Forgot to mention, I am using some MS Audio plugs instead of the terrible RCA's that were fitted to the Lenco. They work extremely well!

One other thing. Whilst setting up I found the arm / cartridge works better without the anti skate device and to my ear does not sound at all compromised for not using it. I don't hear any groove distortion or sibilance what so ever.

I have not serviced the motor yet and although I think it is well within my capabilities I am a little unsure if it is something I should leave alone. It does not make any noise and runs very smoothly but I am sure it is running on its original grease.

My apprehension with dealing with it concerns the fact it is installed using springs which I believe have to be at the exact tension to eliminate noise getting through to the top plate. Also the bearing has to be re installed just so as to not have to much play, 2mm I think.

Can anyone advise me if this is a straight forward service/procedure or am I going to start having issues when reinstalling?

Not trying to hijack the thread, but I too have a problem & need advice with the supporting springs on the motor of my Lenco GL75. (It is replinthed in a heavy laminated plinth with a Jelco arm). It has developed a rattle on the motor springs; if I thump the plinth gently, it stops, but it always comes back. Can I tighten up the springs a bit & if so, how much?

helma
19-04-2016, 14:32
^ Do you have the transport screws on (the two screws with red paint on top of them)? If they're still there (but not tightened of course), try removing them completely and see if the rattle goes away.

EDIT: also check the idler wheel for any eccentricity or alignment issues, if it's bent or something it could excite the motor suspension into some kind of rattling action by presenting sideways forces.

are you still using the Jelco arm with the GL75? It is a possible option I might explore with the Lenco I have as the tonearm I have is a little shabby with the rear slightly bent and poor condition of the tonearm in general.

The Jelco 750 is definitely on my radar.

The M55e / Jico SAS by the way sounds stunning on the Lenco, dare I say even better than it did on the VPI!

If possible could you kindly post a pic of your Lenco on hear so I can see the tonearm?

Hi Jimbo

Not too good with the photo side of things I'm afraid but Dom of Northwest Analogue did it up for me & if you go to his site & click on Gallery, scroll down & the last piccie is my table.

As you can see he cut the chassis so that the arm is completely decoupled & it is a heavy 'Layers of Beauty' rosewood veneered plinth.

It sounds great (when it's not rattling!) like that but I don't know how it would sound with the arm directly coupled to the chassis.

Sadly I missed out on the Jico M55E stylus; I got my NOS M55E plus a second NOS stylus from the US but then Jico stopped making the SAS styli before I had time to order. I hope they come up with a good substitute at a sensible price fairly soon.

I play it with an M97xe with SAS, which is very good. Also Denon 103R and AT-Mono3/LP, both of which sound fantastic. I am thinking of getting the AT-Mono3/SP for 78s but got to get this rattle sorted first.

Interestingly I was noodling round the interweb yesterday and I came across a long thread which had a Jico insider, I think he was an employee, who mentioned there was going to be an alternative in the pipeline but it had to be resolved probably with new materials. I think the Boron cantilever was the issue !

I have spoken to Dom a fair bit, great chap and extremely helpful with the Lenco. I wanted to keep mine original but the arm is in quite poor condition. If I were to have a new arm, probably a Jelco750D, then I would not really see the point of keeping the original plinth. Might just as well go the whole hog.

However I would have to be sure that going this far would really give me a significant upgrade in SQ and was not purely a cosmetic exercise just replacing the arm for something that looked nice. If SQ is not significantly better with the Jelco I will battle on with the original arm, in fact I may try and get an original arm in better condition as I am sure there must be many that have been ripped off Lenco's.

I cannot really make a comparison for you because I was given the Lenco from a friend's attic where it had been lying for 20 odd years, the motor didn't function as the solenoid or whatever had perished and the arm suffered from brewers' droop! As a result I never heard it with the original arm, but sent it straight off to Dom.

However I am very pleased with the Lenco/ Jelco marriage.

I haven't heard the original arm either - the v-blocks were completely shot on mine and frankly nothing about the arm seemed like it would be a top performer, so I made the mounting hole in the chassis larger (SME-style) and popped in a Fidelity Research FR-54. Excellent combo, though some people seem to think it's better to mount the arm on the plinth.

Regards the rattling, I suspect it's an issue with the idler wheel / motor / platter relationship - if the idler is correctly aligned and in good shape, maybe the motor alignment is incorrect, so that the pulley/idler wheel contact happens at an angle. Or I suppose it could be the motor is just too low or high. The drive mechanism relies on the idler wheel 'locking' between the platter and motor pulley by the forces extended to it - the idler wheel spring is there just to make initial contact. If things are aligned badly, it could create sideway forces or the idler wheel might be sort of bumping back and forth between the pulley and the platter, as far as the force is concerned. Maybe that wasn't very well put, the way I understand it when everything is well there should be a constant force holding the idler wheel in place, now if the alignment is someway off, there could be a sort of a "yo-yo" effect in the force and since the platter and idler wheel can't really move, it would then cause extra work for the motor suspension. Basically the idler wheel should be perpendicular to the center line of the drive pulley in every direction.

I hope that makes some sense and I'm not full of it... I'm sure there's a Lenco expert or two in this forum, but I'd guess there probably exists some sort of guide for this stuff over at the lencoheaven forum.

20-04-2016, 12:51
It certainly looks OK, but I will try & check that. I never had the problem until I started to play some 78s; before that it was always dead silent. If I give a light thump to the plinth when it is not playing I hear the same rattle; same thing if I put a record onto the spindle & let it drop, which is what makes me think the motor springs are too loose. Would it be worth tightening them up a bit, say half a turn or so?

I posted on Lenco Heaven, but the suggestions I got didn't seem to solve the problem.

IMO the lenco benefits from a high mass plinth. The fruit box it comes with is not ideal but gives adequate performance. I have two lenco's awaiting plinths and I recently sold my ptp. It's possible to get a lenco to sound as good as a 401 if enough money is thrown at it but it doesn't have that quality feel about it like the 401. The clunk of the on/off and speed selector on the 401 is quality. Doing away with the lenco's speed change and using Nigel's speed controller is much more user friendly.

Sorry a bit late answering these questions. Still on holiday in Germany



So what material are those plinths contructurd from?

The PTP plinths are made from layers of Corian. The 4mm stainless steel motor and bearing plates are beautifully machined into the top layer.

http://i257.photobucket.com/albums/hh229/ZYXlover/PTP%20details%201_zpse0iex6y7.jpg (http://s257.photobucket.com/user/ZYXlover/media/PTP%20details%201_zpse0iex6y7.jpg.html)

All the details are here. http://www.ptpaudio.com/

I use a Nigel's speed controller which is very precise.



That's beautiful, the Phantom looks brilliant on it. How does it sound.

The Phantom11 is a superb arm. Must be the nicest tonearm to use and setting vta and azimuth is so easy. The adjustments are so precise properly set up it allows the cartridge to sound it's absolute best.

I used this arm at Scalford this year with a Benz LPS.


QUOTE=Jason P;753172]Ooh lovely... What's the bottom arm? Looks radical...

Edited to say I see that's the Moerch. Lovely arm.[/QUOTE]

The other arm is a Moerch DP8. I saw a black one which is special order in the states and was lucky to get one.

I use two wands, a high mass precision blue dot for a ZYX 4D and medium mass precision red dot for the Benz LPS

Both arms sound superb on this turntable, the 4D on the Moerch has dynamics to die for.

I hope to have this turntable with the arms at the North West Audio Show in the Horning loudspeaker room.

mint condition, including the tonearm. The guy I bought it off kept it covered up in his hifi room as he had so many t/t s its not had a lot of use. So, not changed a thing for

Thanks Brian it is a real gem of a find and completes the overall look of the Lenco. I am undertaking a little surgery soon to replace the phono cable and plugs as they are in a very poor state and probably don't allow the best from the turntable.

Popped the Lenco on last night and played a few LP's. I also replaced the bearing with a ceramic type from Brian and re greased with Lithium.
Noise floor has dropped and slightly quieter background. I could swear I am getting a tad more HF detail probably due to the better screened phono cable and gold plugs?

Thanks for the coaching. Might get bit more adventurous:eek:

The bearing spins longer and smoother, now you got me thinking of that beefed up bearing plate! The bearing on my VPI is a substantial beast and has some sort of similar arrangement to the improvement you made to your Lenco. I will take some pics of it and post them up. The VPI bearing is also machined from a thicker piece of steel in a bronze sleeve. It is super quiet and smooth but i don't think the Lenco is far off now!

brian2957
24-09-2016, 17:37
Yes I was really surprised when I stripped the bearing and relubricated it with Lithium grease . I was convinced that it would cause drag . To my surprise , the opposite happened and the platter spun ever more freely .

The bearing clamp did provide a further upgrade James , and IMO is well worth the money .

Not a problem with the help James , I'm only returning the favours I received on here when I first got the turntable :)

I certainly wouldn't mind having a look at the bearing on the VPI .

Popped the Lenco into the system so I can set it up and fettle for next weeks bake off.

Listening just now to M55e / JICO SAS playing Malia Convergence. The combination of the Lenco JICO is spectacular with great soundstage and presence in the vocals. All the detail you could wish for with that great Lenco drive. The JICO gives great transparency to the sound and the bass is deep and punchy. If I didn't have my Decca / VPI I would be very happy with this TT cartridge combination.

The JICO beats the Decca for tracking but in all other areas the Decca knocks it out the park.:)

Hi Brian, yes it is indeed perfect and a rare find in new condition. Very occasionally new GL75's are found with all their original packaging. I saw one last year but don't know what it sold for.

These are seriously good turntables and with a good cartridge are extremely capable. I did not expect great things when I bought it but having serviced it and used it I now know why they have a forum entirely based on Lenco's!

Yeah, I overpaid for mine last year but have enjoyed it so much i m not fretting about it to much. Recently bought
a v15 and generic thakker stylus for 66 on ebay, incredible sound for the money, big upgrade I feel from 75EJ.

Do you know if Thakker do a replacement headshell for the GL75? I hear good thinks about the V15, I wonder if it's better than the M55e?

Someone s made a list on Audiokarma. org of the best shure cartridge s. The first 7 are v15 variants and the last 3 are 97 s. Only
someone s opinion of course. I was lucky with mine as some one listed a v15 type 3 as untested on the bay, which I presumed
was faulty but adding the thakker stylus and its worked like a treat. Best 66 spent on hi fi me thinks. Superb sound.

Jim, I've got a V15 mk3 with the best stylus that Shure designed (forgot its name), rest assured that your '55 is just as good if not better. Try and hear one before you buy one, you might be underwhelmed with the V15 compared to your hot rodded '55. Just sayin..... ;)

Cheers Andy thanks for the heads up on the V15. I actually have another plan for the Lenco as I would like to try a MC cartridge with the stock arm. I know the DL 103 works ok but I am thinking of something else, cheap but good. When I get it sorted I will post up my thoughts.:eyebrows:
