Here is a list I made a while ago, while calibrating my IIx. VR7 Is
the top-one.

The pagenumbers are the actual original pagenumbers of the
service-manual. The numbers in the PDF are higher. (Also there are two
versions out there. One is scanned in wrong, the pages are not
straight.  I used the version with the correct scanned pages. The page
numbers differ between these versions)

VR7 V/Octave control              (page 79)    [page 110 of PDF]
VR6 Filter Control Bias           (page 78+79) [page 109+110 of PDF]
VR5 VCA Control Gain              (page 80)    [page 111 of PDF]
VR4 VCA Control Bias              (page 80)    [page 111 of PDF] 
VR3 VCA distortion                (page 81)    [page 112 of PDF]
VR2 Filter Distortion (Res)       (page 80)    [page 111 of PDF]
VR1 Envelope Offset Adjust        (page 78+81) [page 109+112 of PDF]

Hope this helps :-)

Cheers,

Peter Kersten.

Tnx guys, missed that one in the diagnostics section.

Thought I had to look in the (non available) channel card schematics.

Cheers,
Patrick
