Discussion about the Korg PolySix synthesizer

There arent any individual volume pots. It might be well that one of
the transistors which form the VCA is gone. Check Q5 and Q6 (standard
although matched small signal npn transistors "2SC945"). You can skip
the filter chip: remove it and then make a wire from pin1 to pin3 of
the empty socket. Still distorted? Is SAW and PULSE louder than other
voices? This should be easy to find with an oscilloscope and the
schematics, but rather difficult without ...
Good luck!
