As long as you don’t leave me with a mess to clean up, I won’t complain...

I have six new Westinghouse "Reliatron" 6DB6s and one 6BZ7 on their way to Michigan. I guess that answers the 6AS6/6DB6 and 6BZ7/6BQ7A questions.

Pulled and cleaned more of the tubes. To my suprise, the set has more than likely spent some time in Canada. There were a couple of Rogers branded tubes, one Marconi branded tube, and one Electrohome tube, all with mid-to-late 1950s datecodes.

The transformer on this thing is massive, as are the filter chokes, and they run very, very cool. 25 Hz chokes perhaps? Given the area it was found in it wouldn't be surprising.

There was a guy, Robert S. outside of Toronto trying to sell a H840CK15 back in 2000. I passed on it at the time and never heard what happened. I know he was trying to sell it for quite some time. Perhaps this is that set?

Dwight found this set in Buffalo, NY, and according to Dwight, the guy he bought it from obtained it from the original owner who used the set to teach color television repair for either a trade school or a Westinghouse program to teach their own techs in house.

I can't imagine the set being the same one that was for sale in the Toronto area, but anything is possible. There was recently (within the past few years) a Westinghouse H840CK15 listed on Toronto Kijiji. I don't recall the set selling, but it was complete and supposedly had a good CRT. Perhaps that was the set from Robert?

EDIT:

My set is most definitely not the set from Robert S. in Ontario. His set had a developmental CRT (the C73599 proto-15GP22) according to Marlin Mackley's site. This set has a production 15GP22 from the 13th week of 1954.

Marlin's site also mentions that the Wingham museum in Ontario has one with a 25 Hz tranny and 25 Hz chokes. Interesting.

I like to have advertisements for my sets to frame and put near them. I found a number of rather aesthetically pleasing advertisements (Westinghouse ran one hell of a national ad blitz in March of '54), but I also stumbled upon a neat article from January of 1954 showing a Westinghouse H840CK15 prototype and RCA Model 5, as well as articles on Westinghouse color CRT development/manufacturing circa 1954/1955.

Also included is an ad for the lost 19 inch Westinghouse color set, model H890CKU19.










This last Chicago Tribune ad was used in most major cities, with just the name of the city and the copy about the local dealer switched out.

I't looks like a 15" set with a bigger CRT installed. If there was anyone with a good spare 19"* CRT and a 15" westy with a lousy mask and dead 15G it would make for an interesting project trying to convert it to be a 19" set.

*(assuming the 19" they were using is the up scaled 15GP22 electronics magazines of the day mentioned)

I'm quite certain that the jug used was the 19VP22. They mentioned in the dealer sheet for the set that the phosphors were directly deposited on the face of the jug.

I suppose the set could have used the DuMont type 19TP22, which had the CBS style directly deposited phosphors with a 15G style gun. But since the set hasn't turned up, and a DuMont 19TP22 hasn't surfaced, it's all academic.

My folks bought me a new vertical convergence transformer as one of my Christmas gifts, so I'm one step part closer to a working Westy. I have to thank John Folsom for winding them, or having them wound, as well.

Interesting that first article talks about the RCA and Westinghouse having different sized screens, 14 and 12-1/2 inches respectively. Did these sets not both use the 15GP22 (or comparable prototype CRT)?

Just a confused mix of different manufacturers PR. Both had 12 1/2 inch pictures, but some press releases stated the over-all tube size. Where 14 came from (instead of 15) I have no idea.

I just measured the phosphored viewing area of my 15GP22 and it is approximately 11.1 x 8.2 inches, which is very similar to a 12 1/2" Admiral (10.75 x 8.5 inches) and a 12 1/2" RCA (11 x 8.5 inches) so I think that it is accurate to characterize the picture as similar to a 12-1/2 set.

The opening of the double d mask surrounding the 15GP22 is about 12.3 x 10.2 inches.

The glass front panel of the 15GP22 about 14.7 inches diameter and the largest diameter is 15.75 inches to the edge of the welded flange.

I pulled the CRT tonight in preparation for Nick's work in restoring the chassis. Imagine my surprise when I gently set it down on the carpet and heard a soft low "bong", like a distant church bell, emanate from the CRT.

It spooked the hell out of me to say the least, but Nick assured me that at least some 15GP22s do this; apparently he also has a working one that "rings" a bit. It looks just like any other 15GP22. The weld is uglier than hell, and I suppose it wouldn't be much prettier under magnification, but it holds a vacuum. I set it aside in a cool dry corner of my basement. If it still works when I get the chassis back it'll be a miracle. That ANY of them work is a downright miracle.

Ben, What you say is so true. I do cross my fingers every time I turn on my CT-100. It's due for it's monthly test run and will be crossing my fingers, again, this afternoon. Hopefully your 15GP will also crackle on and once again emit sparkling tints & hues.
