The transmitter works with just about anything from a EF80 to 6V6 or even an 807. Its a real junk box project. Im going to do another with an EH90 & EF91.

I built it with one valve (super-regen stage) and it worked well enough. With the RF amp it would work very well and stop the interference that these super-regens produce.
