I once maintained a military radar system that used a traveling wave tube the size of my leg to drive a Klystron tube final amplifier that was bigger than me. The Klystron was in an enclosure the size of a small car that provided magnetic shielding and allowed liquid cooling. Voltage levels in the enclosure were so high that the conductivity of the ethylene glycol based coolant had to be monitored to prevent shorts through the cooling circuit. When the transmitter was tested into a dummy load (itself an impressive device), it sounded like a metal garbage can full of angry steel hornets. Fun times!

Back in the early 70s I worked at a 50kw AM radio station that had an RCA Ampliphase 50G transmitter. The output tubes were a pair of 5671s. They required 15KVDC plate voltage and 11VAC @285 amps for the filament. They needed 1800 cfm of airflow for cooling, were 25" high X 17" wide and weighed in at 228 pounds. I never had to change one, but there was a special lifting device in the storage room in the event that became necessary. The power supply cabinet had huge mercury vapor rectifier tubes that had a purple glow and changed in intensity with modulation. One time a tube in the oscillator section of the exciter went bad and we were putting out spurious signals across the AM band. I was on duty and started getting calls from other stations that something was wrong. I put the backup transmitter online and eventually found the problem in the oscillator section.

[@rocketman221projects]

That's still a little tiny tube. The big tubes were used in shortwave transmitters that put out 1MW or more.

[@rocketman221projects]

@OldWrench59 Search for pictures of the Eimac 8974. It's a big tetrode that takes over 20kW just to light up the filaments. It's surprisingly small for a tube that can put out over 2MW of RF.

[@GeorgeWMays]

This will be great around Christmas time with friends and family all snuggled around the tube to stay warm this Winter.

[@allancopland1768]

At work we used a radio frequency dryer for sewing thread. It developed 30KW of RF at around 27.125MHz in the CB/ISM band. It was water cooled with the anode strapped to ground and the heater cand grid circuiits 'floating' negative with respect to ground. .A BIG triode that had a heater rated at 10V@240Amps. It was a BIG metal cased triode. I can't remember the anode voltage bit it was many KVs. One day, one of the hoses supplying cooling water came adrift spraying the RF deck with water (demineralised!) . The results were quite spectacular and the valve was destroyed pretty much instantly. The oscillator was a simple free-running type. Amazingly for me at least, I couldn't detect any RF leakage at all using my Kenwood R2000 HF receiver placed near the metal cabinet when the machine was running. The internal RF screening was superb with a lot of finger-stock and brass brush seals.. It was a carousel type dryer with the RF fed into a chamber at the rear of the machine to dry the thread which was wound onto 'cheeses' and stacked vertically in threes, with teflon spacers between them and a teflon top cap.. Vacuum was applied as the drum carrying the 'cheeses' entered the drying chamber which helped to force water out. 30KW of RF did a great job of drying the thread! When it failed, replacing the dead triode was interesting. The new triode arrived in a large wooden crate packed in straw. Ww used a forfkift truck to lift the crate over to the machine where we unpacked the valve and shoehorned it into the machine using the forklift truck.. These big transmitting valves are designed to be repairable. Thay can be taken apart and refurbished. I never did find out how much the new triode cost, but was glad the company was paying for it.

We have 'one' of these at work, but in 3-phase configuration for 3x230V, the sections are 115V each, that means a tower with SIX of these on top of each other with a common shaft, driven by a motor. Now *that* is a beast. IIRC it can do 3x230V, about 100A per phase maybe. I don't remember the brand, but it's US made, some time in the '60s or '70s.

@@stargazer7644 I have made mistakes fixing old TV's and felt the eht (25Kv) off the cap of a CRT. Makes you hop and probably not good for a weak heart, but no real current capability via the tripler and eht rectifier. A little more painful than a car ignition jolt. If Mr C puts 12Kv on the anode of that tube it can pass 1.5A. You won't say ouch if you get across that. You will pass a killer current in no time at all. Only the really old TV's which derived the eht 10kv or less directly from a transformer winding could pass enough current to be potentially lethal. Those tests if they involve high anode voltage and current capability should be setup behind a faraday cage in what we called a rubber room.

A long time ago I was a tech looking after a critical computer system using hundreds of valves. (tubes). We understood that the thermal shock of powering on and off the heaters is what reduces the MTBF of tubes. Best practice was to leave the heaters on all the time, but if we had to power off the heaters then slowly reducing the power was as important as slowly ramping up power. Nice to see Mr Carlson following this.
