19CK1 for Christmas!

Actually, the 19VP22 has the same glass to metal flange seal like the 15GP22, but with the phosphor dots on the face of the CRT and a much simpler curved shadow mask construction. In the photo, you can see the flange shrouded by its polyethylene shield.

RCA was obliged to license this construction from Hytron (CBS), from which RCA developed the 21AXP22. I was not until the RCA 21CYP22 came out that there was an all glass color CRT.

Harry, if you want to make a socket adapter to test the 19VP22, it uses the same socket as the 7Jp4. You would need to add/move some pins to your socket.

Thanks John for setting me straight on the 19VP22's metal/glass construction. I do remember that a long court battle preceded CBS Hytron collecting any royalties from RCA. I think their court victory came after CBS Hytron had actually left the tube business and tons of 21AXP22s had already been made and sold.

Except for the Ca. 1956 Westinghouse 22EP22:

I was going to make essentially the same post regarding the 23EP22, except that it seemed that the date of its introduction had fallen later than 1956 and perhaps later than the 21CYP22.

Hi All!

Thanks to all the well wishers..it was a nice find, and a set that is really nice to look at...a really pretty blonde set from the 1950s, and a color TV that is a significant find, which, as mentioned, is not an RCA...although finding the RCA prototype was a heart pounding experience

I haven't had much time to check it out..thanks John for the CRT testing advice...and thanks Steve for all of the advertising & tech info of the set!

As for becoming a collector, it seems we collect too many bills to keep TVs...but temporarily, it does look good in the living room! I'll do a bit more research, and then decide what will become of our beauty...

Yes, and when that CBS-owned patent expired in 1972, CBS thanked Peter Goldmark and his Laboratory by forcing Goldmark out of CBS.
