I've been looking for one for ages. They're out there, but at outrageous prices. ManualsPlus sells a very nice reprint manual with schematics.
If you're patient, I just started building a replacement using most of the original circuitry. I'd be happy to make board files available, or a board at cost. It might be a few months, though; things are very busy at my real job. The degausser is quite simple. High degauss provides ~330 ma, low about ~17 ma initially, with an exponential decay. The decay constant is 100 secs. There's a 20 minute timer that terminates the cycle. There's a DPDT relay which switches the current direction through the coil that toggles every 2.5 seconds. (Cheap H bridge). That's it. I'm replicating most of the analog current source circuity, but replacing the analog 2.5 sec and 20 minute timers with a uP. I'd also be happy to send you a copy of the schematic. If you want it, send me your snail mail info. I'd recommend the manual, though. It's very nicely done and costs $25.
