Archive of the former Yahoo!Groups mailing list: Discussion about the Korg PolySix synthesizer

Hi,

After bringing my dead Polysix back to life (Battery leakage,
faulty SSM 2056's) I decided to give him a completely new
calibration.

There are 2 points in the service manual which I have
difficulties to understand:


- In "KLM-366 check and adjustment", point (3) "VCF RESONANCE
adjustment":

"Check CN05-7 with DVM and adjust to obtain 8.000V +/- 20mV"

What am I supposed to adjust ?

- In "KLM-367 adjustment", point (4) "PW/PWM check and adjustment":

"...confirm there is a DC component of +0.2 ~ +0.5V"

My Polysix shows an offset of about 1.6V ... any ideas ?


Thanks in advance for any hints...


Regards,

Andreas.
