[sdiy] Oscillator caps - please help!

[Antti Pitkämäki]

Hi,

Thanks for those who answered, you were of great help. By choosing the right 
cap I just want to ensure that the oscillator(s) stays in tune. I'm not too 
conserned about affecting the sound in this case.

Yes! I've played combo organs for several years, and yes, the more stable 
the better. I wanna spend my time grooving, not tuning ;) Also the old 
tuning coils are fragile - breaking them is a nightmare.

Some later combo organs use a chip that generates all the notes, and which 
has all the notes perfectly in tune with each other always. Maybe this might 
be just a little bit too stable, but on the other hand, no need for tuning 
and breaking coils.
