I built a two valver about 65 years ago using an RF 25 radar front end for the chassis these were around for a few shillings in those days. Line up was SP61 strapped as a triode as a leaky grid detector plus regen with another working as an output pentode to a three inch speaker.HT came from a 6X5 which worked off the same heater supply as the others. Strangely enough this set worked as soon as plugged in with a three foot aerial, I had fun with this for years and then switched on one day to find the rectifier anodes glowing cherry red. I never bothered to investigate I was too busy as a very junior hospital doc by then, should have used a metal rectifier I might still have the set now!.
