Thanks to everyone for their responses thus far, I am kind of relieved to hear it might be the tech. But after closer inspection myself, it does appear there is some corrosion on the voice board. Under the specific voice that is not working, Voice 4.
To answer your questions Don:
- The LFO to VCO and Pitch Bend not functioning is affecting all Voices
-The Tech said he did not fix anything
-He specifically mentioned a trace missing/pulled from the KLM-369 board, but later mentioned he noticed a bunch had been pulled.
-He said he noticed the corrosion on the back of the KLM-366B board, specifically around Voice 4, the one that is not sounding. In a closer inspection, I noticed what could be corrosion, but I am no expert.
The picture attached is an image of the KLM-366B board, notice R136.
