How would they do this in practice? If it had to be done in a hard
vacuum, how would you transfer the heat away from the valve to cool it

let it cool down by radiation, obviously keeping it out of sunlight
while it's up there. ;-)

And why would they do it to a rectifier tube? What would they expect to
gain?


Your money. if you are gullible enough
