I think it was my bad PCB printing though. Hi Seb,

unfortunately I haven’t and it has been quite a long time since I tried. I think it was my bad PCB printing though.

I finished a Yusynth VCO but none of the waveforms work (I managed to get a blurry 5Vpp square wave from the square output once but it disappeared again) Thanks! Hi, did you find the error?

Two of the part select buttons (the orange ones that light up) are a not working 100% (they do eventually work, but I have to press them alot harder than the other buttons). I have downloaded the service notes, but it's hard to identify the correct board to access (or the procedure) from there. Do you know if its possible for for a mere mortal (ie me) to access these buttons to either clean the contacts (if this will help) or replace them (without me destroying the whole machine)?. Really hope you can help. Hi Synth frog

Unconnected fills are something best avoided with pcb design. Nice website, by the way!

I sometimes use an eraser for ballpoint pens to lightly sand the contacts on the pcb. Use a dry cloth to get any grit off the carbon part of the pad. That's just my 2 cents.

Trying to search for info to fix them got me here. Any thoughts on how to fix a pad that is registering several hits or not registering hits properly? Any info be appreciated. Thanks Hi, Great post :)
