Westinghouse K840CK15 Restoration

[Steve D.]

Hey Marshall,

Love those beautiful 15GP images. I brightened up one of them to show the mask being highlighted.

Happy Holidays,
-Steve D.

You are by no means overstaying your welcome! I, too, marvel at these pictures. I'm surprised that Sandy G. hasn't piped up yet about the excellent "lollypop" color.

BTW, I checked IMDB and there is no reference of Barbara Bain ever appearing in Hogan's Heros. There is a strong resemblance, though.

UPDATE, DECEMBER 26, 2019.
I hope you are having a happy holiday. Season’s greetings to all. Just a few more screenshots to show this 66 year old set’s capabilities. No adjustments were made to the set during these screenshots which show subtle differences in color rendering like a good color monitor should. Although the Westy is not a monitor, it is my understanding that the first color monitors used in the 30 Rock control room were RCA 15GP22’s in CT-100’s.

You are correct Marshall.

CT-100 color receivers used as monitors at the NBC 30 Rock studios 1955, flanking a newly installed RCA Victor 21CT55 color receiver, center, employed as primary feed monitor. Also a 1955 photo of the CBS NYC transmitter control room located in the Empire State Bldg. CT-100 on wheeled dolly on the left used as a monitor. Click images to enlarge:

I have never seen the color photo. CBS must have installed the CT-100 reluctantly.

Marshall,

I wondered about this myself. CBS had already purchased RCA color broadcasting equipment. Perhaps this was the most convenient way to supply color receivers for their early color monitor needs . CBS did, shortly, purchase RCA TM-10 15" color monitors when they became available. CBS color control room. Click to enlarge:

Happy Holidays Marshall, thanks for continuing showing photos. That Westy has amazing color gamut for 66 year old technology. I hope 2020 is a year I can either get my Zenith 1968 console to run or more work done on the RCA CTC9 running. I envy you as your retired and have more time. I’m just enjoying my oldest running set from ‘75 a Sony KV-1920. It was my first ever Trinitron. Lol I now have many Trinitron’s Still looking for more.

UPDATE, JANUARY 1, 2020.
Since the beginning of this restoration, we have been wanting to create this video. Most of you know the story. For the record, the NTSC color format in the United States was formalized December 17, 1953 by the FCC, (Federal Communication Commission.) NBC broadcast the first nationwide color telecast on January 1, 1954, but no one was able to see the Tournament Of Roses Parade in Pasadena, California, in that year because no color sets were available to purchase except one set*. RCA and NBC however, arraigned to have public showings of the parade by invitation. Most showings were private for broadcast personnel, television industry dignitaries, friends and families. These viewing locations were typically at television stations, hotels, convention centers and movie theaters. A few television appliance stores had prototype RCA, Admiral, Westinghouse and Raytheon color sets available for the public to see on the day of the telecast.

Westinghouse as well as other manufacturers were in a race to bring to the public the first color television receivers for sale. *Admiral was the first with it’s C1617A on December 30, 1953. Twenty seven days after the first nationwide color telecast, (the parade) Westinghouse offered for sale on February 28, 1954, the H840CK15, initially only available in New York and New Jersey.

Today, January 1, 2020, 66 years after the first color telecast of the Rose Parade, it gives me great pleasure to present this video of the parade on one of the first available color television receivers available in the United States, the Westinghouse H840CK15. It uses the RCA 15GP22, the first production color CRT. I’m very thankful for Mike Doyle’s restoration abilities, completed September 30, 2019. Without his work this restoration would not be possible.

What a great effort to preserve this priceless bit of history and show us the parade. I was 9 years old and watching the same parade on grandma's CTC-7 in the day. We 11 cousins surrounding the set were amazed. It still looks like the same grand display of color RCA planned. Thank you Marshall and Mike.

I clearly remember watching color TV in the fall of 1954 at my uncle's house about
1/2 mile from the transmitter of WBAP in Ft. Worth. I asked Santa for a CT-100 for Christmas,
but did not get it until 60 years later in summer 2014. I'm still amazed at
how perfect the color pictures are on it (using modern cameras of course).

Thanks to Dave A I was able to watch actual real OTA TV (Ch. 39) on my CT-100
until about two months ago (if I could stand QVC channel programming, of course).
That's gone now. It does, of course, still recieve Ch. 39 with a perfect picture
when transmitted OTA from about 20 feet away.

John, Dave, thank you.

These sets do evoke fond memories. I had a similar experience with my Uncle, it was in 1956. We were invited to dinner, after dinner we all gathered around his new color set and a ‘Special’ was on and wow, just wow.

You'd think that CBS would have RX90s or at the very least be using the 15HP22 tubes in the units they had in their studios.

Those are by far the best pictures I've seen from that series. I missed out on a couple ct100's back in the day

Just saw this. Thank you! Not happy you lost out on the CT-100’s to be clear.
