[sdiy] Octave Cat modulation weirdness

[Travis Thatcher]

I recently restored an Octave Cat SRM and it was working pretty well.
I replaced nearly all the CMOS and recapped somethings. The only thing
I couldn't perfect was the scaling when you switched from mono to poly
mode but that didn't bother me - just meant I had to adjust the tuning
of osc1 by a step.

The weather here in central VA as well the rest of the Eastern US has
been a bit humid to say the least. Yesterday I fired it up only to
find that osc 2 is constantly getting an amount of modulation from the
LFO, even with the modulation pot turned completely off. I checked and
leg 1 of the pot still has continuity with ground. I'm guessing a cap
some where finally bit the dust, maybe egged on a bit by the humidity
in the house. Just curious if anyone has seen anything like this. I'm
going to open it up tonight to investigate.
