I'm slowly repairing a 102100, which seems to basically be the same synth with a few minor revisions, and I'm having a problem with the pitch modulator board. The fast and medium slide settings do not slide up to the correct pitch. When you push either switch, the base voltage on the control voltage line goes up, so when a key is pressed, you get a slightly off pitch. Since it uses the exact same board as the 102200, would you be able to check a few voltages for me? I'd like to know what you have for the voltages at the medium and fast slide inputs to the board when their buttons are selected, and also when no slide is selected (so at the inputs of resistors r80 and r83), and the voltages for the same three buttons at input of c17. If you could let me know I'd really appreciate it!
Thank you,
Mark
