Richard,
How about an ARC welder! I'm being sarcastic, the tube I'm
looking at is 7.5 V at 100 Amps on the filament. I'll probably use
a balanced neon for the plate, but I'll need to experiment and find
what filament currents will work. I already recognize that if the
current is to low, it will take forever to heat the tube.
Big, Red, HV capacitors. Burn baby burn.
