found a PAIA 4700

Hi,
I just restored a PAIA 2720. I’m looking for some help on a problem with the 37 key keyboard controller. I calibrated the VCO (0.625V & 2.5V) with no problem. Next I adjusted the Pitch control to lowest C and Highest C on the keyboard with no problem. When it came to adjusting any of the 37 individual trim pots, I got no response from any of them. Need help here. Thanks

if none of them work, there's likely to be an issue with the main wiring to/from the voltage divider PCB
