Do you have continuity of D03 from the switch through KLM-369 to KLM-367?
I just had a Polysix with a non-working EG mode switch and a problematic
attenuator; turned out that a trace on KLM-369 (the left board) was broken
(in my case P10 was the culprit). Both KLM-370 and 369 can be affected by
battery leakage.
