Right now, the tube is a big unknown. I do not intend to just plug it into a tube checker, because if it is gassy, the heaters will likely blow. I suspect that I will bring up the heater voltage slowly and monitor for excessive heater current... if I get up to 6.3V with normal current and a nice orange-red glow, I will then use a crt checker.
The pinout and voltages of the crt look about the same as a 21AXP22 so I suspect that the guns are very similar. One thing that has me worried is that the tube does NOT appear to be fritted together... So how was the front panel attached to the funnel?. Indeed, quoting Peter Keller again: "Corning Glass Works developed the frit-seal process which was first introduced in 1958 for the all-glass 21CY22 color picture tube." I hope that they did not use the same process that was used on the 15GP22s. When I obtained the set, it produced a fair picture, somewhat dim, and convergence was always a problem. The previous owner left the side control cover off, and said that he often fiddled with the convergence, which changed during operation. Yikes! Hot chassis and all! jr |

Many of us have been waiting for this day! I can recall some false hopes when folks found Westinghouse sets that looked identical to this one but were B/W. Very strange that they didn't dress it up. Westinghouse seems to have always been an also-ran; perhaps had their promotional abilities been a little better they would have sold more. I wonder if they ever had Betty Furness selling these on TV?

That is why I think the Motorola sets were so great... the gorgeous 19" just shouted COLOR! and even my 21" has that nice 3 color treatment of the tuning knob. jr |

Glad to see that one of these sets survives in
outstanding cosmetic condition. Check out the Westinghouse 22" color receiver pictured on my site from a Dec. 1956 Magazine ad. -Steve D.

Thanks Charlie, I edited my previous post. The link isn't working. You can go to my site and scroll down to the Westinghouse ad.

At first sight, I would've never guessed that was a color television.

There were two 22 inch tubes, one made by CBS and one by Westinghouse. I have had two Westinghouse and one CBS sets reported to me, but these are the first pictures I've seen.

Steve McVoy, did the individuals who reported sets to you give any indication of model number or cabinet type? jr, many thanks for the wonderful photos - this is certainly among the rarest of the rare! Did you happen to notice if the tube map includes a model number, and if so does it match the one on the model number label? |

Thanks again for the comments!
A few answers: No, the tube layout does not show the model number, my Sams Photofact (#357-1) indicates that it is for "Models H-22T155 H-22T156, H222T157A (Ch.V-2293-11,-31)". Underneath the tube layout chart written on the cabinet is "6-56" ... cabinet mfg date? Yes, some of the caps look newer... there are also several tubes with date codes in the mid 70s so it appears that some service work was performed before I got the set. Interesting about the CBS-Hytron 22" crt... I have passed along this info to Peter Keller. Has anybody seen one? jr Last edited by jr_tech; 09-18-2009 at 01:37 PM. Reason: spelling |
