[sdiy] Looking for Polymoog service manual/info

[Bob Weigel]

I'll try to help with this when I have a bit of time as I told Mega in 
email.  One more thing...I'm not sure but...the brown 'extension 
cord'....hmm.  Does it look factory?  Of course..in a polymoog...that's 
kind of hard to tell I know :-).  But I'm...not aware of anything like 
that on mine.  It's been a while though. -Bob
