Sq's system.

[sq225917]

So, a little more to add. I printed a strobe disc off and took a look. No matter what I did with the settings I had a little bit of 'gallop' in there with the Project motor. It was slight enough that i couldn't hear it, but I could see it. Step up transformers arrived today, they are nothing fancy just 15VA 230/2x18v transformers with the secondaries wired together to give 110 on their outputs (inputs really) when fed 18 volts from the PSU.

Sure enough with the LP12 motor back in that gallop has gone from the strobe, it's rock solid, not one 'segment' of drift in ten seconds of rotation on a 200 segment strobe disc. You can do the math.... Ok you probably won't, it's good, very good. 45rpm is similarly ridiculously spot on.

I recorded the test tone yestrday with the old motor, I'll do it again today with the new one, but my eye/strobe tells me this is the most accurate the speed on this deck has been so it'll be interesting to see if that is backed up by the specs.

Another project done. I reckon the total build cost on this once cased will be about 300 quid, which is pretty spectacular when you consider the results.

[YNWaN]

I've just been round to Si's house with my super accurate strobe and disc, the new power supply does seem to work very well - very stable. It looks like I will also be following this path.

[sq225917]

Ahah, young jedi the power is strong in this upgrade.

[sq225917]

So it looks like shit but it works really well...

Though looking at the video, with the benefit of a static camera, I can see it is very slightly fast since I put a new belt on. I better dial that out.

33.333rpm should be up in a minute or two


https://vimeo.com/76130604

[YNWaN]

Now that is good :) - both speeds!

[sq225917]

Yeh, 10 seconds with not one mark of drift on that 360 mark/rev strobe disc equates to better than 0.0005% absolute accuracy, or about 33.333rpm. I don't think I've ever seen a review of a deck in any magazine where the measured absolute speed was that good. Hell, some of them are off by more than 0.1% a lot more. In fact thinking about it wasn't that 25k+ Systemdek off by almost 0.5% ?

Any bouncing in the image is coming from the fact it's a paper strobe disc and not flat to the platter.

I'm very pleased with this project.... :smug:

[The Black Adder]

And so you should be... excellent!

[YNWaN]

I'm very pleased with this project.... :smug:

Yes, you should be - I think the speed accuracy is even higher than you suggest.

I think I'm going to do a super accurate strobe disc from 3mm acrlic (or possibly laser laminate).

[NRG]

Great result, where did you get the controller board and s/w from Simon?

[sq225917]

I doubt you'll get it any better than that Linn one of yours Mark. I'd have to use full of gloss card to get even anywhere near that good, and I'm guessing the resolution of my printer is higher than the laser cutter, 1200dpi actual.

Neal it comes from Daniel, (Meldano) and is supplied as a pcb + programmable chip pack. He supplies a BOM for the build. There's nothing in the build that you can't find in the UK and it's easy to build and test. It'll do 7-24v as standard and is happy doing 110v with step-ups, (these are just boggo traffos from Farnel, nothing special.)

[NRG]

Excellent, thank you Simon.

Looks like she makes a f-in brilliant cake trap.

No sooner does one Krell KSA 200 leave me then another arrives to replace it. The guy who bought my Krell KSA200 already had one. He purchased the other one that the guy who I bought mine from had. it worked for a couple of month then started humming like a bugger and finally threw the protection relays last week. So he's bought mine and left me his other one to do a full strip down and recap on.

Funny old world. Hopefully it's just old caps that need doing, nothing has ever been replaced in this one. If it's actually a transformer fault that shows up under load then he's f_cked, cos there's no way to rewind these buggers- and there would be no change from £1000 for a replacement from anyone who could handle the task.

There's a lot going on in my system, regular coming and goings. An awful lot of diy and more than a fare bit of level headed measurement and investigation.

Take today for instance. I finished building another pair of these for a German gent and yesterday i took in another KSA200 for a strip down and service.

Where do you keep finding the paradise boards Simon.
I didn't think they were still available.

[sq225917]

They aren't, this set had already been purchased by the owner he just hadn't got round to building them. He had seen my builds and Mark's cases and decided to have them built up. I offered to build them up for a modest amount for my time and the price of the upgraded parts. There must be loads of them out there, the GB was 300 sets and so far less than 50 people have posted pics of completed units on diyaudio, I bet there are hundreds of sets still in boxes waiting for the owners to start the onerous task of component matching.

Total build time including matching for this set will be about 30 hours.

[sq225917]

Blimey it's been ages since I've done anything in here.

So to update.

The Paradise remains, No 31 is sat in the conservatory awaiting me to get my arse in gear and complete the final wiring. Hopefully that'll be out the door next weekend. It's the first one to get local supply decoupling on the underside of each of the lytics on the main boards. We'll see how that works, the numbers say it should be audible, we'll see.

My Muse Model 200 gave up the ghost, pre-amp section died, power amp part is fine. if anyone wants a massive 200 Watt class Ab balanced input power amp with 30db of gain let me know, there's a deal to be done there. It sounds mega, but I've moved on.

and I've moved to this.

https://c2.staticflickr.com/2/1834/29042867387_0ec6a606c6_b.jpg

I had a BPBP Bruno Putzeys Balanced Pre in my set-up for over a year, but I've built a new one and added in a Khozmo relay stepped attenuator. It's a lovely thing with remote control 62db and mute in 1 db steps and sounds like nothing.

https://c2.staticflickr.com/2/1839/42171756880_ff4463fd86_b.jpg

I'll get round to casing it up in the upcoming weeks. It now has a massive external +/- 15v DC PSU for the main amp board and another 5v LT3045 reg unit for the attenuator.

https://c1.staticflickr.com/1/935/43932414872_f9339e67ff_b.jpg
https://www.flickr.com/photos/59684834@N08/43932414872/sizes/l

The other new arrival is a pair of cases for my power amps. I've been running a pair of Mod86P power amps, with another pair of boards lying spare to build them up into a full on dual mono block BTL set-up that should deliver 200w at vanishingly low distortion, 0.005% thd at full power, lol.

https://c1.staticflickr.com/1/853/30090471108_6c5bef1516_b.jpg

There's a soft start board to add to this lot yet. Each monoblock will be 400VA transformer running 40v rails and two stereo 80w Mod86p (parallel) chip amp boards run in BTL mode.

https://c2.staticflickr.com/2/1838/43240392904_57e2024e25_b.jpg

The cases are the Chinese sourced version of the Goldmund Telos chassis, big, thick and with a 240x 180mm heatsink on one side. Once they're all built up they should be about 32lbs a side.

Of course I have to get that last PAradise out of the door first.

Hi Simon

Looks like some great projects you have going on.

Any more information on the Bruno Putzey's pre and how you have done things please? Are you thinking of offering such a pre (with remote) to punters like me?

[sq225917]

Edward, there will be a current group buy on diyaudio.com for the BPBP pcb with all the SMT stuff assembled, I'm not sure what price they are from NAT currently, it needs about another £40 of parts to complete the main pcb then the attenuator is on top of that at circa £250. Throw in about another £150 for psu parts and you're looking at £500 just in parts cost, not included cases.

It's a fully balanced/differential pre-amp. It'll take an RCA/XLR input but that would be a waste of a great pre-amp. It has two inputs, one output, controlled via physical switch. I figure if I'm swapping between record and digital then I'm going to be stood in front of it to take a record off or put one on so a remote switch seemed like overkill.

I have no real idea what I'm doing with cases, the psu will be hidden away, the main boards might end up going in an end grain laminated ply chassis with acrylic front and back panel. Pre amp needs 150mm wide 90mm high and 160mm deep so I think casing it up shouldn't be a task.

When It's all assembled I'll do some proper annotated pics. If you like the look of it I can help you assemble one, it should be plug and play apart from the chassis.

[Edward]

Thanks Simon for being so generous in your explanation. Looking forward to the annotated pics when you have them. I'm not sure I'm up to assembling it but lets see. Don't need remote switching, just remote attenuation control.

My interest was piqued when I saw you mention Bruno Putzey who is doing some pretty edge things in the audio world and getting wide recognition. Love to have a listen to his Kii Three speakers (doubt I will ever afford them though).

[sq225917]

The Kii's are very good.

[sq225917]

Finally getting round to doing the casework on these. Back panels all done, all pcb bits done. Just need to drill the heatsinks to clamp the main boards and then fit the gubbins.

[sq225917]

Cheers gents, I know this doesn't look like real progress but it is. Main amp boards fitted, PSU board fitted, front panel led's test fitted, trafo test fitted. Very pleased with the clamps for the chips; I was going to try and blind thread the holes but in the end the simple solution was to grind the bolt heads down until they slipped in between the fins of the heatsinks. Neat and tidy and best of all, easy to do with limited tools.

https://c2.staticflickr.com/2/1883/30561631748_ab2a7fd76f_b.jpg
Traffo and soft start boards to fit and wire up, then signal wiring to do and we're done. I've ended up cadding out the layout of all the parts to get the shortest cable runs possible first time round. Measure twice, cut once.

[Edward]

How long did the casework take to turn up?

Here's the only channel, with neater wiring. I'll rewire the other channel tonight to match/mirror.

Sent from my VKY-L09 using Tapatalk

[sq225917]

The boards aren't available any more, the designer stopped making them when they stopped making the LM4780.

It's basically a pair of these https://www.neurochrome.com/parallel-86/ run bridged for each channel, but with a larger PSU. 400va and 66,000uf per channel

So that's a 60w stereo chip amp with both channels run in parallel on each pcb and then a pair of those pcb's run in bridged mode inside each chassis. About 150 watts and can deliver about 10 amps. It's pretty stiff and has vanishingly low distortion, real SOTA numbers.


More importantly though, it looks the bollocks.

4x Mod86p boards, as bridged mono channels £400
2x PSU boards £80
2x Toroidy 24v 400VA transformers £130
2x chassis £360
2x soft start boards £70
Sockets, wires and mounting hardware £90


Not bad for £1000 and 100 hours build time.

Similarly I ballsed up the PSU case today. Exact same thing, I forget about the folded edges on the case, so had to chop bits out for the pcb legs etc.

Finished the pre-amp tonight, or at least this first iteration.

Think it needs a deeper volume knob and it either needs an internal bracket for the display or front mounting with screws to match the final front panel mounting.

Sounds ace though

Not screw mounting, that will look clumsy, I will come up with an alternative solution. I can remake the volume control but you need to buy me a bit of Delrin (allow 20mm minimum to allow me to grip it - so at least 50mm long piece of bar). I don’t have any appropriate stock.

The front panel likely needs redoing too as the A and D seem a touch big and too far apart.

Wot? No sliders? (-:

The A and D are perfect...

For the display mount is it possible to go half way through the front panel, then i could push fit a plastic standoff with a short screw stub into the hole. The pcb part only weighs 20 grams.

I'll order the delrin...

Just in case you need help in cutting the delrin the technician in the following vid I'm sure will be helpful. :lol:

I like the looks of that, and as you say a deeper volume control will do the business.

I'm pleased with it. Marks coming round later and were going to tweak it about for a v2. I might throw a dc blocker into the psu case as well for the raw a.c. feed.

I like the design very much.

So. vol pot is moving 5mm left and moving to 20mm depth, AD is being flipped over and moving 5mm to the left and Mark's going to do the panel in a different material with a back mask
