Probably. There are old TV enthusiasts just like there are old radio
enthusiasts, although they're not as common -- the technical
challenges involved in TV repair are a little tougher, and a lot of
people who don't blink at working with +450 volt B+ supplies are a
little wary of multi-kilovolt CRT anodes. (Justifiably so -- tube
sets have a lot more capacitance in that circuit than solid-state
ones. A solid state set, treated incautiously, can throw you across
the room. A tube set can be lethal.) Replacement parts for TVs are
also harder to come by, especially CRTs -- their bulk means they were
a lot less likely to survive in storage, I think.
