The RCA Theremin Registry project was started here at ThereminWorld in 1996 and has been maintained with member input since then. The Registry project has now been picked up and expanded upon by long time TW members and friends Mike Buffington and Andy Baron.
They are launching the new site at RCATheremin.com today!
Besides tracking the current location of known RCA theremins, Mike and Andy have added a lot of information on restoring the RCA and on Lev Termen's original theremins.
Many thanks to Mike and Andy and congratulations on the new site!
