More Synth Repair
Here are a couple of nice shots of the back of an Oberheim SEM. The color-coded Molex connectors which route signals to and from the SEM have wonderful, gemlike hues. In the second shot the new electrolytic cap is evident (the big blue can).
This is an SEM rev “A”. Unfortunately, in my 4-voice I have this one rev A board and three of rev B, for which I have no schematics. This caused me to waste a bunch of time yesterday. If anyone out there has SEM rev B schematics, please contact me!
I’m taking all these pictures with a really weird digital camera: the Polaroid X530. It’s got a strange type of image sensor in it from Foveon, which isn’t used in any other cameras except one Sigma SLR. It’s pretty cheap, focuses like crap, and takes photos which are sometimes really janky, and super grainy in low light, but have an amazing film-like quality sometimes. I think of it as my digital Holga. Click the top picture for the big version.

I got a nice response from Kevin Lightner via the Matrixsynth blog. Finally this beast is back together and sounding better than ever.

You should send some of those peices of Twizzler candies sticking out of your SEM pcb with your friends. Those are some OLD candies, though.

Nice Shots.
Electronics can be so beautiful, like scale models of cities or organellla. Too bad I know next to nothing about them (electronics). I suppose that’s something I could remedy.

Hey R-
Have you pinged resources on the Analogue Heaven and/or Synth-DIY lists yet? And without having to subscribe you might find links to such in their archives?
If you haven’t already tried…
