Yamaha CS80

Hi Christof...

Thanks for the reply. Would you by any chance know the poti's number
(VR?)...? Looking at the circuits diagrams - I think the SM1 board in
the SY1 and SY2 are very similar... there are 3 (possibly 4) presets
mentioned in the manuals. VR1, 2 and 3 are mentioned in the
calibration section - and I think VR4 is actually shown on the layout
but not mentioned anywhere in the text...!

But I can count 7 presets altogether on my board. So it might be
either VR5, 6 or 7...?

Cheers,
TOM
