This is somewhat MISC but I recently heard that the Russian military is using tube tech for some of their military gear...could be total bullshit but then again also have heard that our military still has tube gear from the old days thats still classified...so maybe not total Bullshit?

Tubes are better suited for high frequency and high power than solid state devices, or at least that was the case as of several years ago.

I think most stationary high power radio stations use tubes at the output.
When in doubt, add resistance.

Also think there's something to do with EMP weapons and tubes being more robust and I guess you just replace the tubes if an EMP blows them out?

Maybe the worlds military forces are just gear-ophile hipsters. :lol:

The old FPS-90 radars threw a solid megawatt of radiated power out. The thyratrons were glorious in those beasts.

The last shop I worked in handled the depot level repair, refurbishment and modification to the systems associated with the FPS-77 radar. '50s era tube technology. Brutal tube beast of a power supply that used 5@ 6336-B, twin triode tubes, rated at 35watts per section. The thyratron was tube. I can't remember the specs or model but x-ray radiation was emitted so exposure was limited when the transmitter was firing. One TRACALs radar I worked on originally had a gas tube thyratron that ended up with a thyristor replacement. It looked cool and no xrays.

As Curtis pointed out hi freq and hi power is where gas thyratrons rule.

I don't know if they are really all that super rare but this does look to be in super condition but not for that much.
