Discussion about the Korg PolySix synthesizer

Hi,

My PWM Works !!! my problem was a network resistors ... after replace, it's work fine !

I have another questions :

for PW calibration, on service manual Page 19 / Paragraph 4.2 :

"2) Adjust VR3 to obtain +2.2v"

I obtain +2,2v but i no longer sounds if the potentiometer on the front between 7 and 10, Is this normal?

Thanks,
Richard
