Some things can't be rushed. I packed away a fortune worth of audio equipment the moment my wife said she was pregnant. It took me two decades and the need to do a loft conversion before I finally dug out the bits again. Most people had thought I had got rid if the stuff or had just lied about me ever owning any of it. So Marco might be on the same type of trip:).
Out of interest, things that I packed away:
2 x Micro Seiki MA-505 MKI
2 x Technics EPA-501H
1 x Micro Seiki DDX-1000
1 x Ariston RD-40
1 x Sony PS6750
1 x Mitsubishi DA-10
Plus a few dust arms. Since then eBay has enlightened me to the curet day value of all that stuff:). Glad I didn't flog them then.
Mike,
Yep, it's half done. I've just got the 'interesting' bits to add ;)
I've got too many things on right now to finish it, but don't worry it'll be posted before your next birthday :lol:
I'm also trying to get the Yaqin sorted.
Has your deck 'emerged' yet from its slumber?
Marco.
PS. Sensi, did you read my reply about the EPA-501H?
I did. Got a few things to take care of, which is taking up space on the same table I use to take pictures. Once that is out of the way I shall do you the shots.Quote:

If so then you can buy http://cgi.ebay.co.uk/ws/eBayISAPI.d...e=STRK:MESE:IT
It is then upgradable to four :smoking: seperate power supplies, as is your want.
Sensi,
Nice one. Keep me in the loop :smoking:
Mike,
Looks like Richard has sorted out the phono stage side of things. For the cartridge do you fancy a coil or an MM jobby, and what type of sound do you like?
I can then recommend some suitable cartridges within your budget :)
Marco.
Interesting!Quote:

2. Would it be possible purchase the board and four PSU's together, and at what price?
3. If I purchased four PSU's I assume it would be preferable to use four separate transformers, bridges etc. Yes?
Cheers,
Mike.
Well, it depends on which phono stage I settle on, but considering present budget constraints I expect to be looking in the MM playground for now.Quote:

Don't dissapoint me I thought you knew what was what and could use a soldering iron.Quote:

In the pic and in the offer there is only one regulator board, but each of the gain stages can be powered seperately so if you wish to power them seperately you would need four regulator boards. PSU are £190 each, your money is gone!
Any techie has got a couple of trannies lying around and a few caps I though you were one, I was trying to help but if you want it built then you pay for it built.
Doh!.... I'm a clown and should pay more attention to what I'm typing!
Please re-read questions 2 & 3 and where it says 'PSU' please insert 'Reg'.
:doh:
I kind of knew what the answer to Q1 would be, but I thought I'd check anyway. One never knows, maybe you could be persuaded to sell a Phono2 board! ;) (he said, expecting the answer 'No'!)
Come on it is a simple regulator board, a couple of resistors and comping caps one side of the chip a couple the other, when you get one you can copy another three on some veroboard or similar. I want to see you do some techie.Quote:

You could go whole hog with Shinko res and top dog caps, you could change the op-amps but I have found no better, they are just selected for the phono 2.

And there will be lots of celebration and :gig:
Okeydokey.... :youtheman:
When I get started I'll start a new thread and documant 'The Build' with photo's 'n stuff.
I think I'll have to source some nice boxes for it all to live in though rather than the scabby bits of tat I've got lying about. It'll have to be a two box affair too, it'd just be rude not to!
Night night.
First lesson - never put a transformer (especially if it is a frame) anywhere near a phono stage, even moving magnet. Two boxes are essential unless you are only using one small 50va (or under) torroid, and then aligned so the field null points to the phono pcb.Quote:

Rewinding back past the electonics for beginners class, fascinating as it is... What bloody sound do you like so I can recommend a bloody cartridge. I won't bloody ask you again! :lolsign:

Remind me again of the maximum budget you have available for the cartridge, now that Richard appears to have saved you some money by going down the D.I.Y route for the phono stage. Suitable recommendations will then follow :)Quote:

Let's say, hmmmm...... £150(ish). Oh, and it has to work well in a Hadcock GH228 (earlyish one with aluminium armtube).
:scratch:
P.S. Why do people bid like this? :
http://cgi.ebay.co.uk/Denon-DL-160-H...QQcmdZViewItem
You can buy a brand new one for less than £80!
A lot of people have no idea of the value of what they are bidding on and assume it must be a bargain if it's on ebay. I've also seen cases where identical items from the same seller have been available as either auction or "buy it now" on seperate listings and the auction item has gone for a higher price!:scratch:Quote:

Hmmm...... I've found a Goldring 2500 for a pretty attractive price. I liked the 1024 I used a couple of years ago, I wonder how they compare?
Decision, desisions...

They are extraordinarily good for the money, and as good as anything up to £1000! It's the usual 'the best stuff goes to the non-UK market' scenario. The AT-33PTG is a veritable giant-killer, and it has the balance of sonic virtues you're looking for. It is also far better than an OC-9!
Another option is the Denon DL-110, which is a high-output model you can use straight into a MM stage. It has a higher compliance than the DL-103, which I would normally recommend, but which wouldn't really suit the relatively low-mass of the Hadcock.
Otherwise, any of the Clearaudio MMs in your price range would be good, or the new Ortofon or Goldring MMs, or perhaps some of the Grados - most of these are within your budget.
Marco.
Hmmm...
Interesting choice, and a bit of a new one to me.
Too late though, I've already ordered a Goldring 2500 (I got bored waiting :ner:).
Yes I'm going out on a limb here but I think it's more or less impossible to audition one first in the deck/arm combination I'm going to be using for the foreseeable future.
LOL. Nice one - I hope it works out :smoking:
And that would be the SL-120, I presume?
Marco.
Or Lenco GL75... Winner takes all!Quote:

Anyway.... I'll start a new thread to continue this sometime soon and delete some of this 'Mike & Richards bantering room' stuff to allow the thread to at least look like it's on topic.Unless anyone would like it to remain 'as is'?
'Later' folk's, I've got some serious cooking to do, a nice Kashmiri Rogan Josh doesn't cook itself you know! ;)
ta ta for now. :wave:
Anyway back on topic
I have just taken delivery of an ex DJ 1210.
It will be a little fun project in my quiet times (if I ever get any). I will mod and rebuild it using principles and things learned in the design of the NVA senior T/T (never to be made again) dating from 1990. But sorry they will be my secret :ner:
C'mon Richard, get those hands in the air and kick up a fierce one!
:gig:
Excellent, this is very exciting indeed, as it appears that no one else in the UK has really put their hand up and had a bash at one these sleeping giants. I know this is Kevin's (KAB) fear, but I guess it had to happen sometime.
I'm sure a few of us on here will be very interested in your findings. :)
Yes, Richard, do let us know how you get on :)
Are you retaining the stock arm?
You *might* even manage to report on your findings before I get round to writing my review! :lol:
Nicky boy,
I took delivery today of one of Thruno's '3-piece suite' brass counterweight balances. It's excellent, but you're lucky you have that extra weight on top of your nude 103 Pro because if I use all three brass weights I can only get 2.1g VTF with my Denon, and that's with all three counteweights pushed as far forward towards the pivot point as possible...
I'll dick around a bit at the weekend and add a touch more mass at the headshell to enable me to use all three counterweights, and thus allow me to position them ideally (as close to the pivot point) as possible, and obtain the correct VTF. I usually find 2.6g ideal.
I just thought I would report on this :)
Marco.
Its my fun so :ner:Quote:

I have just finished my last bit of fun / project of taking the cheapest CD player you can find on ebay, originally sold by Richer Sound - the Eclipse CD101 - you can get them on ebay for about a tenner - and rebuilding it with killer powers supplies and some component changes and it makes a CD player to kill for. It just happens to have one of the best sounding transports ever made and is extremely long lived and reliable. Anyway now it no longer has a mains lead but has a seperate PSU box or two seperate box PSU's depending on how far you take the mods. I have surepticiously bought 10 of them on ebay over the last 6 months, so keeping a couple for myself there will be 8 going up on ebay at some stage.
C'mon all you amateur techies. Buy some of the cheapest **** you can find on ebay and have fun. It is the techie version of Jerry :lolsign:
Marco, yes lovely pieces aren't they. It was a bit of guesswork really, but luckily it works out fine for me. I'm not butted right up against the pivot, but pretty close.
I havent spun any vinyl for 7 weeks now, the chap building my pre has had family illness problems and is running a month late. I'm beginning to climb the walls. My Quad actives are much better now they run from dvd player rather than ipod, the same chap is going to mod these too in the near future, so I should have an excellent system by the summer.
If you want a quick peek inside my PS-1200 PSU just let me know ;)Quote:

But no direct copies, mind! :eyebrows:
The thing about the SL-1210 is its amazingly accurate speed stability and virtually non-existent W&F, which has a remarkable knock-on effect in various areas of its sonic performance. Most T/Ts these days (even very expensive ones) are just toys in comparison.
Marco.
Nick,
You get away with it because of the extra mass on top of your 103 Pro.Quote:
Marco, yes lovely pieces aren't they. It was a bit of guesswork really, but luckily it works out fine for me. I'm not butted right up against the pivot, but pretty close.
Yeah no doubt, mate. I'm sorry to hear about the delay. Hopefully you'll also be able to take a trip up to sunny Wrexham :)Quote:

Not in the slightest bit interested in what is in your PSU. Amateur prat arounds are good fun but don't compete with the *master* :ner:Quote:

Your description is common knowledge and is really gobble de gook "amazingly accurate speed stability and virtually non-existent W&F" how are you measuring it, since whan has any test equipment told you anything sensible. Torque my man Torque, that is king in car engine design same in turntable motor design. Forget your bloody stupid BHP. In a T/T it is stopping and starting torque, so does that mean when you press the button, nah!!! it is happening everytime a pole passes the coil. The trouble with a direct drive is that it is *never* rotating at the right speed. It averages the right speed, but you don't necessarily notice it as it happens in a split second. BUT it effects how you percieve music. Guy was muttering about it in the version that Technics did for the cutting lathe. Needs much bigger motor with many more poles. I am playing at simulating that.
LOL. We'll compare T/Ts then when yours is finished ;)Quote:

I agree with you about torque. Measurements? Look at the 1210 spec in the manual!
My (very good) ears and my experience with a multitude of T/Ts, though, tell me all I need to know about the deck's performance.
And I won't ask you again, old chap, are you keeping the stock arm or is dementia addling the grey matter? :ner:
Marco.
Why on earth would he want to?Quote:

Actually, if you dispose of the rank-rotten stock internal wiring and phono cables and replace them with Cardas sliver linz and good quality phono interconnects, fit a decent counterweight balance and headshell, and add some silicon fluid damping, the Technics arm is very, very good :)
Build your own, by all means, and I'm sure it will be excellent, but don't automatically assume it will be better than the modified stock arm I've described above :smoking:
Also, fitting a decent mat is a must. The standard rubber thing is shit and does next to hee-haw (a rather quaint Scottish expression) to damp the ringing platter.
Marco.
Mmm... I use to have a brand new Hadcock GH242 Integra. I sold it. Do you wonder why? ;)Quote:
