No tubes, but the 833 is a glass transmitting triode good for a 100 watts, with something like a max plate voltage of 4000 volts.

Here's a pic of one 833 in one of the ungodly expensive WAVAC amps....

100 real watts of triode...sounds like fun.

100w in SET...dayum. Could run electrostats with that

Does the 833 have a thoriated tungsten filament? Definitely looks like a transmitting tube...only ones I've ever dealt with personally were some 3500-Z's in an HF radio amplifier. Did something like 1.5kW full carrier on AM, those things would light up the room at full power.

Looks pretty burly... Designed for HF, LVHF bands.....

I'll throw on a picture of my 10K-dub transmitter tube when I get a chance.....
