- The light in the volume pedal does not work
At first I suspected all these problems had a different cause. But studying the schematics learned me all these problems had something in common.
They are fed by the -20V supply off the power supply. Doing some measurements on the power supply I found out the -20V supply was completely dead.
Then I found a fried resistor (picture red arrow). Seems I have shorted the -20V circuit while working on the organ. I remembered the first day I was working on the organ the power light was still working, at some point it stopped working. I thought it was just the bulb that had gone dead.
Exchanging the resistor with a new one fixed the problem.
