Don't ask why but I am thinking about building a tubed Theremin. I did a very perfunctory search on the web for schematics and came across ones as seen here: http://www.antiqueradio.org/pe0455.htm and http://www.antiqueradio.org/ei0161.htm
Just wondering if anyone ventured into building one and how it worked out.
This is hilarious: https://www.youtube.com/watch?v=xcTPRjiCs6s
