I was just installing the resistors when I noticed something a bit odd... It may not be anything, but it concerns R211 & R210 in the Quantizer A/B section. R210 is 10k and R211 is 100k - I would have assumed that both quantizer circuits would have been identical. I took a look at the original ARP sc...

Nice one Andy! Pretty quick too (re your questions on adding bands), are you going to mod this one or leave it as is? Now that it's up and running, I'll start fiddling with it - maybe by adding 2 extra BPF cells to each channel (very easy to do with this layout) if that improves things, I'll build ...

Re: UK Pots Source?

So where do UK DIYers get their pots from? All the specs I've seen lately say Small Bear. There must be somewhere in the UK (please don't say Rapid). I get them from Tayda or Futurlec - delivery can be slow sometimes, but bulk prices can't be beaten, and they all have the shorter shaft (so no hacki...

I've just made a couple of slightly modded 702 PCBs - I'll give the 3046/heater combo a try and see what happens :wink: It's a simple case of replacing the transistor pair from the u726 with the pair from the 3046, and adding (as ringroad1 mentioned) the Doepfer heater.

Matthias Becker said that you need a handful of Roland 100m oscillators to do what you get with two System 700s. Can't imagine why he'd say that... as far as functionality goes, they're the same (except for the fore-mentioned lack of Sine wave). I've checked the core circuits... they're the same to...

It is possible to replace the 726 with a 3046. Rick over at Frequency Central did it for the 100m (System X) VCO, initially he didn't use the heater - but he does now, via a simple add-on board. I've got 3 of them and they're rock solid. I'll dig out the details as soon as I'm fully awake... EDIT - ...

Both the System 700 and 100m's VCOs are very similar, but the 100m lacks the sine wave. Frequency Central have the System X VCO (a clone of the 100m) in Euro format. They also have a DIY kit - I used 3 of them in my Minimoog(ish) clone because they are seriously good. https://farm8.staticflickr.com/...

Thx for the info... Dave, I think you're right. I'll double up the cells. I've already sorted out and ordered the alternative cap values.

Why does this always happen to me? First the TTSH, and now a Minimoog clone.

I could have saved so much heartache and frustration, if only I'd waited for someone else to do the grunt-work :doh:

All 3 are gold plated, I just meant that the top one was a straight wire. Use the heaviest plain G string you can find (.024) - As I mentioned, the ones in the pic are flatwound (Jazz Strings), so they're slightly thicker than the heaviest plain, but I find them easier to handle, although they are m...
