Lee,
This was the most expensive TV receiver then. This cost an extreme fortune then. Few people could even nearly afford one. CRT tubes on this set were regrettably an Achilles heel on these sets. Many survivors don't have a functional CRT which hasn't gone to air. Not much unlike the RCA CT-100 of 1954 fame. Both have in common many non-working CRT tubes and difficult to impossible rebuild options. Just some perspective. I have one of these Dumont Royal Sovereigns stored away with the exact same problem. Like yourself, I desire a solution.
