Why are 1960s Zenith TVs so rare on the west coast?

Zeno brings up an interesting point. I currently somehow have 2 Packard Bell roundys.
One is a 1962 and looks like RCA shipped them a then several years old stock CTC-7 or CTC-9 chassis (I haven't dived in to the resto on it yet since I'm waiting on the previous owner to send me parts he forgot to load) PCBs and all, and then PB modified it to accept their computer light tuner and remote control system, suck it in a custom cabinet to accommodate the tuner and remote and made it work with a 21FJP22....

My later 1964 PB is the one with the doughnut chassis that is built like a Zenith (and like the rectangular PBs Zeno is thinking about) the circuits while RCA influenced don't appear to be a direct copy of any RCA chassis.

The PB roundie I am referring to has an upright doughnut chassis that swings out. I am not sure where to source a new CRT for it.

Never seen a P-B roundy. The real P-B's I remember had an L shaped chassis.
Looking from back the power stuff ( HV, Vert etc) were on the bottom &
the low level on the left behind the tuners etc. There were a few I remember,
hybrids were taking over. Dont remember the swing outs but maybe I
never needed it to fix anything that deep.
Best way to find the source of a CRT is the EIA number on the CRT tag.
That tells you who built it. Ex #274 is RCA, 343 Zenith, 1101 Rauland div of Zenith etc..
CRT's seemed to be sold at different grades also. Best ex is Sanyo built
19" Sears sets using Sylvania jugs. @1980. Most got H-K shorts BUT
I never seen a Sylvania of that vintage short out.

Time for a

Spare NOS roundy CRTs are extremely rare and sought after. If all you want is a good roundy CRT look for a CTC-16 or a less interesting clone (especially one with a wrecked cabinet that's priced cheap), confirm the tube is good with a tester before you buy it, then harvest your treasure. It's also doable to stick a brightener on the old tube, stick it in the donor set, make the donor set work well enough to sell and flip the the donor for a profit... I've done it before.

Sometimes they show up at TV swapmeets and sometimes if you know local collectors you can ask your way into acquiring one.
