Re: Suddenly out of tune -but still problems after changing PC-1 and R93

2008-08-24 by Andrew Jury

Hi Peter,

Lucky you! My processor board was totally frazzled by flying nickel 
cadmium powder! Just wanted to check I understood you OK with regards 
to the controls. I have had a quick inspection of my Polysix and have 
to tell you that I concur with your dc voltage readings around IC31. 
we have an extra days holiday here in the UK tomorrow and I will have 
a bit more of a poke around inside. I'll let you know...

Cheers,
Andy
