Hi Tom,
in my CSY-2 the board is named SK, and it's the VR3 poti ( see linked images, marked with a yellow arrow ).
Probably there is a difference between the SY and CSY models. As you can see on the
2nd picture everything is build with descrete components except the VCO module.
I think in the SY models there is probably more modularized stuff...

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
