lifespan transmitter driver amplifiers

Not sure how to put this but, Back when whole tv stations were tubed how frequently did the finals feeding the antennas need to be changed? I mean weren't many of them on the air 24/7 before the solid state age where some were even still used?*

Just stands to reason that by the nature of a thermionic device at those power levels it would always need swapping out.






* I'm starting a group about t.v. sign-offs etc and would appreciate any feedback on the subject...
