Subject: Pwm leaking to affect VCF cutoff

Hi all,

I recently got a Polysix with visibly repaired corrosion damage. However, the memories still don't work (unable to save). This does not worry me as much right now as the problem that the PWM-lfo is affecting the VCF cutoff, especially when the synth is cold. The MG-lfo also slightly affects the VCO pitch regardless of setting. Everything else is actually fine!

I read some similar problems experienced here, but could not find a definate solution. Where do I start looking for the problem, what do I need to check? Is this some common problem?

thanks, radek
