[sdiy] SSM Question

[Tim Curtis]

Hi Everyone -

I'm in the process of trying to resurrect a Rev. 2 Prophet 5, and I have
a couple of questions regarding the SSM chips.

If I put a buzz box on the voice board power terminals I get a buzz if
some of the SSMs are on board.  Does this mean that they're likely
shorted out, or is it a property of the chips?

Also, can anyone recommend some simple (I'm a moron) circuits that I can
use to test out some of these SSM 2020s, 2030s, and 2040s?  I've got
some extras here but I don't know if they're good or not.

Thanks,


Tim
