Subject: TIME SENSITIVE REPAIR- Polysix tuning problem question

From: Bernie GREENBERG <ptsaudio@sbcglobal.net>
Date: 2011-03-11

I am working on a Korg Polysix with the usual tuning problems. I replaced the
photo coupler with a VACtrol and resistor mod and still unable to tune
keyboard. The high tuning control, VR2, seems to do nothing. I have tried
different resistor values with the VACtrol mod and still have tuning problems
with the high end of the scale. TIME CRITICAL repair and going out of my
mind!(BTW- no battery corrosion at all!)KLM367 aligned perfectly, KLM 366 board
is new production. PLEASE HELP!!! Thanks in advance for your time.
