Almost completely off topic, this reminds me of the experimental radio transmitter I made when at school. it used a pair of PT15 with suppressor grid AM modulation. I had the PA until recently. it was made on part of an old deuce chassis.
I wish I still had those valves: https://frank.pocnet.net/sheets/139/p/PT15.pdf the same kind as used in 1154 transmitter in WWII aircraft.
Kind regards, David.
