Congrats on fixing the hum. I've just spent a sunday afternoon with my Optigan and it's running pretty well now. Some of the chord buttons and backing track switches aren't working, and just getting access to the board looks involved. The reverbs not working either, but I suspect it's just shorted. After some rubber renew on the idler wheel and 3 in 1 oil on that axel, it holds pitch well. Jamming on the banjo / organ combo just now was awful fun!

1) crackle/hiss
2) repeating ticks
3) other notes in the background
4) buzz

Does the volume pedal change the noise?

I'm having trouble with the keyboard section of my optigan as well. The first ten keys play perfectly but from the eleventh onward it sounds like there's a cacophony of other notes in the background. I've noticed that the key it starts on is the first key of the second couplate resistor. Maybe the final two couplate resistors have gone bad?
Thanks all!
