[sdiy] SSB Banana polysynth

[Tom Wiltshire]

Does anyone have any documentation for this beast? Or know much about them?

Specifically, I’m interested in how the voice Pitch CVs are generated. From the era, I’m guessing DAC->4051->S&H, but I haven’t even seen the main board, let alone the schematics, so it’s real guesswork.

I’m trying to help a customer debug one. They’ve got one that was stripped of CEMs, so they’ve put Alfa chips in it. First thought was that the Alfa chips are either faulty or not totally compatible, but it doesn’t look or sound like that to me. I suggested that there must have been a reason someone gave up on repairing it and stripped it of valuable parts, and that we should find that reason.
