I thought that i would make this module to aid in osc tracking calibration. I also thought it would be fun to make pcb's for the sockets and rotary knobs. It worked out quite well with just 8 jumpers.

Here are the pcb design for anyone who is interested. I used the sockets from thonk.co.uk.

I've been waiting for a +/-12v adaptation of this module for so long! Is there any change from Yusynth's original PCB? |

Hey tomodular,
this really shouldn't be much of a problem. In fact, I'm working on this (somehow). Since I don't really trust my PSU that much, I'm trying to adapt the circuit to run on 12V (either driven by regulators or with 12V zener diodes). If you've got a trusty 12V PSU you shouldn't even need these mods -- and can work with the original PCB design.
Anyway, the trimmer cascade is offset by a handful of resistors. Adapt them to a 12V based range and you should be good to go. Throwing it into LTSpice I calculated for these resistors:
R3 = 12k
R4 = 4k7
R5 = 130k
R7 = 130k
R8 = 390R
R9 = 390R
Everything else is more or less independent of the supply voltage. If you can't properly trim the NULL OFFSET, try to lower R15 a bit (and the respective other 1Meg resistors from the trim pot to the opamp).
If you haven't solved this yourself already and try my suggestion, please share your results!
All the best,
helix
PS: I'm working on a stripboard layout (original and modded).
