Isn't it amazing where valves crop up and the things they inspire? Take a look at this picture:-

Is it just me or does that space helmet remind my readers of an 833A triode as well?
The 833A is a directly heated HF power triode with a thoriated tungsten filament that can deliver 1000W RF from a drive of 38W throughout the entire HF band. Alternatively. the 833A makes an efective room heater / audio amplifier with a pair in class B delivering up to 2700W. Quite an achievement from such a small package when introduced during 1941

It's a meaty old thing the 833A just look at these ratings, talking of meaty things, I might get Mrs Mullard Magic to model a similar ensemble, I think I have an old demijohn somewhere that should fit over her curlers and hair net.
