[sdiy] Minimoog Overload Light Stuck / No Sound

The usual reply to this with real minimoogs is 'reseat all cards'.

Check connections between boards I guess.

I'm thinking of regulating the unregulated ones using a 7815 / 7915 pair just to see if I can get rid of this problem (then I'd go back and see if I can figure out how to leave them unregulated but get them to +/-15).

I don't really understand the theory of operation for it, and I suspect it's not just the overload that's a problem (otherwise I'd expect to have some sound -- at least when I use the A440 reference or noise generators, which I have tested independently).
