Subject: [vintagesynthrepair] Korg POLY-61 pitch drift problem
 
Hi, I'm trying to repair a POLY-61 for a friend. I have very
little
experience at this.(I replaced the battery in mine so he
thinks I'm a
genius).
Anyway, I replaced his battery,but
some of the ni-cad acid found it's
way across to the voice board. I
had to replace a transistor and some
other things. I thought I had
it right, but after a few minutes voice
2 and 3 begin to drift up
in pitch to no end. I don't know if I used
the wrong parts or if
something else is wrong.

Any ideas?
