Discussion about the Korg PolySix synthesizer

Hi,

I have a problem with PWM, i don't have output.

On KML367 On IC15, pin 1, i don't have waveform output, just a 2.2v signal, and on IC20 pin 5 don't have a waveform output, just linear output (~1v). (i have compared with functionnal Polysix )

I'm lost, i don't know where to look for solve the problem. If you have an idea ?

You have a Hight-quality photo of PCB (no populated), the photo on Jed Jorgensen website is poor quality and it's too hard to read the component value ?

Thanks, Richard

PS : Sorry for my english
