For all that noticed...since I make my living selling vintage TVs, I usually can't afford to 'collect' the TVs...or I'd have loads of TVs and no house
For everyone that wondered, I did plug in the TV (briefly), and the vacuum tubes lit, including within the high voltage box, but the CRT did not. The CRT filament is either broken or burnt out, even though the tube appears to have vacuum--no white deposits on the neck, and no deposits that are visible inside the tube.
So, this will be a problem for restoration (unless RACS gets going), but I have to say, even when I sold the RCA prototype a couple years ago, that developmental CRT was working, but recently failed...so it has become an unfortunate reality, that most of these glass-metal early color CRTs might not make it much longer.
