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

Hi everyone;

while trying to calibrate another Polysix I noticed that C16 wasn't
installed on KLM366B (read: the newer voiceboard revision).
Crosschecking with a number of other voiceboards it looks as if that cap
was installed on some but not on others.

If I'm reading the schematic correctly that cap should go between IC25 pin
3 and ground; and a preliminary observation of the PCB shows that to be
true.

Any idea if there was a reason behind this (and if so: which one)?
