About 16 years ago I bought a PolyMoog Synthesizer from a Pawn Shop up in Brighton. It was in good shape and came with the PolyPedal, but didn’t have the legs or power cord. I found a computer power cord in the shop and asked the broker if I could give it a try. At first he was reluctant, but then allowed me to try. It acted as if it had a stuck key; I knew this could be a much bigger issue than just a key; so I talked to him and got a really good deal on it!
I bought the schematics and operations manuals online and took it apart and looked to see if it was something mechanical or “simple”…but I was unable to figure out the issue. I figured I’d send it out to a tech sometime; but given its weight I wanted the tech to be close to home. Meanwhile, I found a PolyMoog Road Kit on eBay and I won that auction. This parts kit was essential for bands who were on the road with one of these beasts, so I was told. This came from a former employee that worked in the Moog Trumansburg Factory. He included with this auction lot several Moog schematic blueprints and an EMU modular catalog!!! *BONUS* 🙂
Fast forward 15+ years… I found a great tech here locally just a few months back (Chris Rowland, offbeat electronics) — who I highly recommend, btw — who has put to good use that PolyMoog Road Kit. I hope to get my Moog back in pristine working condition here shortly. Meanwhile, I finally took some photos of these schematics that I have framed and hanging in my man-cave. Click on them for a larger image; and some didn’t come out as clear as I wanted; if you want higher resolution let me know and I’ll work harder to get a better shot!
Here are some more schematics and a great article.
