I guess that's one of the RCA 630TS clones, eh? I kind of like the cabinet.
Those tubes must be obscure. I didn't find them in the first two online references that I clicked.
What's the big attraction? Scarcity? Used in things like theater amps that certain people go nuts over?
Maybe you should flip the tubes on eBay and repay what you spent for the TV. Some people seem to pay almost anything for a tube labeled Western Electric
