Satellites are withstanding these on an almost daily basis, for years,

however, laying hands to that technology might be a bit of a different

As far as I know- none of the satellites are using vacuum tubes .
That's the reality .

Dream on. Just about every satellite in the sky uses vacuum tubes. The
TWT (travelling wave tube) is still the way to generate high, reliable
power for space-borne transmitters.
