Hi friends! I wanted to build the world's most powerful plasma flamme of 60 kW but for now, I settled on power 21 kW tube tetrode The power dissipated by the anode GU-61A 30 kW Operating frequency 70 MHz filament current 130 A Filament voltage 8 V high voltage rectifier assembled on 6 Gazotron 15 Kv 10 A YouTube videos
I just got my radio license, so let us know next time you fire it up, and I'll try to listen in from here in America. At 60KW on 70MHZ, if you get any kind of propagation, I might be able to hear it fire up!
