It's all built! I have no way to test it though, because I don't have anything that makes noise! I'm in the middle of moving, and all my studio stuff is at the old house.
I have a mic and a crappy stereo preamp here though, and running the preamp out, into the SSL left channel, then the left out back into the other channel of the preamp, and watching the meters on the preamp, it is definitely passing audio, and looks like it's pprobably even compressing!
BUT, the meter on the SSL no worky
When I first put it together, I let the magic smoke out of one of the VCAs I did some tracing and figured out one of the 5534s was bad, replaced that and the voltages on the VCA pins matched, so I popped in a new pair, and no magic smoke this time.
Next I'm thinking I may throw the function generator into it, and scope the output, see if I can actually SEE the compression, and check for distortion and frequency response if I can get either of my stupid scopes to behave.
PICS!
