50MHz transmitter power amplifier



This home-made amplifier for 50MHz uses the Russian ex-military GS31B triode tube, producing about 500 watts output. It really is a fantastic performer. I remember some noteable reception reports of my signal, namely, "599+++ on my ground plane", "599+30dB" and "remarkable signal", from Belgium, England and Norway respectively !
