    Yep. HF 10kw.
    Most people look at those kind and say "that's not a tube, where's the glass".

      Yeah they use ceramic instead of glass for shielding and other nefarious purposes.

      Out 500kw LF transmitters had tubes that were 48" long and weighed 50lbs.

      The sockets and associated circuitry was all solver plated straps, bolts, etc.

      We didn't maintenance with tools similar to the ones for working on automobiles.

        I wonder if they are using something along the lines of a vintage Champ circuit in those... it probably wouldn't be exact (sounds like you have a solid state rectifier), but I'm guessing the circuits are similar. I may see if I can track down a schematic and take a look...

          Yes, it has a SS rectifier for sure. I like the amp, plenty of chime, but I think it compresses to easy.

            Biggest thing I've dealt with is FM 5K transmitter and old AM Gates BC-1 that was all tube. Nautel spoiled me with their 1K all solid state AM transmitter. Small market radio is kinda' fun until it isn't.

              Yeah I think SS work up to a certain wattage, after which tubes take over due to the large voltages involved.

              I used to use a fluorescent light bulb to check the transmitters & couplers for RF leaks!

                I almost bought one of those before I got out of the last band I was in. My main function was keyboards but I also played guitar and the sound guy was mic-ing my little '59 Gibson Skylark amp. It sounded great but I was always concerned about my little vintage amp getting damaged in transport etc..

                Does that thing sound pretty good?

                  I haven't tried one yet, but a lot of people really seem to like them. They're super inexpensive by tube amp standards...
