Westinghouse 22" rectangular find - caught in Audiokarma limbo!

[jpdylon]

stunning to see a set like that - working to boot!

well done, sir.

I don't believe it!Finding a set like that is impossible-AND IT PLAYS,TOO!!!

This has me inspired to get the one I used to own working... It's in the hands of another Los Angeles collector, and he's 50/50 on letting it be worked on. I checked the CRT, and it's OK. I Variac'd it up, but the selenium rectifiers were acting up, and I never went further with it. I didn't realize they were so desirable at the time. Heck; I should probably have kept it, and I won't upset myself nor anyone else by blabbing what small price I sold it for... I'll talk with the owner, and see how he feels about it now.

Wow! Another one!
My guess is that there are more out there that have been overlooked, because they look so ordinary, and are not clearly identified as "color".

Any vendor recommendations for NOS tubes, Caps?

This one is the mahogany table model; in very nice shape but missing the back cover. I got it in the late 80s, and sold it to the other collector in the mid 90s. I've mentioned the set on AK, but it's been a long time. I think that with yours, the total known may be 3.

Radio Daze & Justradios.com are both good for caps. The latter can be slow to ship because they are in Canada.

Lots of places to get tubes; you might want to post an ad here with any needs. I personally have lots of TV tubes, more than I'll ever need.

(lots as in many thousand)

Yesterday, I was looking thru the manual that came with my "Dandy-Dapter" crt tester adapter. There was an extra sheet in there that appeared to be an updated list dated 1983. I was surprised to see there was actually a listing for the 22EP22 tube. It showed the pin-out being the same as the roundie tubes.

Edit: Got a scan of the page. I'm surprised they didn't just do away with the 22ep22 listing being that it was such a big flop from the beginning.

It's the same base, and I believe the same gun.

This thread is just amazing.

I have to wonder why, with all the black & white rectangular sets out there, that the rectangular color set didn't take off. You would think the roundie really, should never have happend.

What a cool piece of rare history. I have to say it is probably up there with the CT100 or the CBS sets. Just too cool

Well, consider that the R&D that went into B/W CRTs naturally began with round screens, narrow deflection angle, and big necks. Not until the electronics were fully mature and reliable did R&D advance into developing rectangular, wider deflection tubes with smaller necks. The same evolutionary sequence was naturally followed in developing color CRTs. Advancing from roundies to rectangular/ wider deflection/ flatter screen tubes brought on new challenges with convergence and particularly the pincushion effect. Pincushioning becomes problematic with wider deflection angles and flatter screens- http://www.tpub.com/content/navyict/14120/141200340.htm which requires dedicated correction circuitry. Thus the big-necked, narrow deflection roundies had to serve sorta as "proof of concept" in color just as had been the case with B/W.

It is interesting that the more famous 15GP22 didn't "make the cut".

The sheet I posted was only a loose supplement page in the back of the dandy-dapter book. There is a listing for the 15GP22 AND 15HP22 in the main list of the book. You'll notice that sheet is missing many of the roundie numbers... they are in the main part of the book as well.

Also, I bet the 19VP22 isn't in there either. That, and the 15G, are very different from the 21(xx)P22 roundies, whereas the 22EP22 and the Toshiba 13" big-neck tubes have the same socket & guns as the regular roundies.

The rectangular tubes never worked right - convergence was the problem.

Gee. What if....
