Assuming they still exist and are interested.
Have you ever looked at the cost of refurbished ordinary ham radio
transmitting valves capable of half a kilowatt?

Not that I have, but I hear that new ones are often crap since the Chinese
never really test them and the assemblies can be poor quality in plating
and construction, but there aware still some big triodes around ex Russian
military that can be pressed into use and the only issue is supplying the
heater current of several amps.

Dunno about vales for Ham use but the prices they charge for much bigger
valves will have a shade more care lavished n them!..

Here you go, for a look at the place that uses them excellent PDF called
Droitwich calling here worth a look!...
