Tech & DIY / Schematics
Here's a list of various types of theremin schematics. You'll find tube theremins, transistor theremins, optical theremins, beginner, and advanced projects. If you're not sure where to start, we suggest reading through our theremin construction forum to get an idea of which schematic might be best for you.
Note, we've moved schematics and technical information for RCA theremins and the Keppinger theremins to their own pages.
Hand-drawn by Bob Moog, these schematics will give you insight into Prof. Theremin's original design concepts. schematic page 1, schematic page 2. Also available are the technical notes Bob Moog wrote while working on her theremin. Adrian Bontenbal also provided some additional tech notes on this circuit with details that are hard to make out from Bob's schematic as well as some bonus circuits.
"Cool Jason. This is ROSS MARSHALL.Just uploaded my old theremin videos.Plus my new TUBE THEREMIN by John Polstra- who amazingly lives off on the Lope..."
"Anyone have an idea what a 91B would be worth these days ?"
"This seems like a most worthwhile project. I am curious as to why no one has expressed any enthusiasm so far. "
"Coil in resonance."
