Have seen similar tube in RF induction heater, sounds like a
water cooled triode of 5-10kW plate capacity.
Assuming not gasey and fils ok would make a good power tube
for a BIG 10-20kW tube coil. Fils on a tube this size would
require power in the 200-500W range (12V-at- 30A or thereabouts).
You need spec info on tube. Check EIMAC website and ask for
tech info (EIMAC is handling Machlett toobs). You would also
need plate water cooling jacket and gasketing assembly, high
power power supply, tank components, etc. This would
NOT be a beginner's tube project. :^)
