Does EMP effect tubes?
I was told that it does not which is why people are encouraged to have tube Ham Radios.
However, I do not know if that is just “knowledge” based on a scfi book from the early ‘60s, where the USSR ‘dropped/exploded’ EMP bombs over the US/world and their computers were unaffected as they were all tubes.
“Does EMP effect tubes?”
It does, but the tubes don’t care. It can arc and do little damage to a tube.
Tubes operate on the order of 100’s of volts. A (damaging) arc in a semiconductor junction can occur on the order of 10’s of volts
