Ham use? No! Time Owned: more than 12 months.
The tube is meant for commercial broadcast which means very long life with very reliable service. The tube is relatively cheap considering the 5-10 kilowatts that can be delivered. Using this tube for ham use is stupid unless you want to run illegal power levels. Then why stop here. Maybe a 3cx20000 might be better for all you illegal hams and cbers. 350 watts to heat the filament and a large chassis and blower would be required. Any normal use of this tube for a ham amp is retarded. The theory that an amp with huge power capability used at ham power levels will provide service that will last a million years is dumb. These amps tend get dismantled in a short time while lowly SB220 last 50 years.
