Which brand is this color TV?
 

I found a photo on a scientific journal of this color TV, but I can not see that brand and model is. Can you help? thank you.

I think it's a commercial monitor of some sort (Conrac, or?), or maybe a TV repair school home-built. No tuner (?). No color TV of that era had a swing-out chassis like that, that I've seen.

may be a monitor for exercises in a box of walnut wood color glossy? under the screen there is a plaque but no one reads what's written. now I go to see if it really conrac
thank you for hours Fernando

Notice the rectangular tube set in the background.

yes, the background you notice a monitor TV studio (not square tube, however!) but the two in the foreground are certainly consumer color TV. the image the small Indian child I saw it on other magazines. certainly belonged to an experimental transmission of colour TV. I do not know whether European or American.

The CRT bezels are the same as an RCA CTC-11, also used in many clones. The chassis, though, is something special.

I think it is a monitor also, the tech's left hand is adjusting 1 of 3 small knobs, on the front panel. None of them look large enough to be a channel changer. This must have been a very high end monitor made to show video for very important people, presidents, diplomats etc.
p.s. looking at the front bezel, it looks like a 4 letter name or abbreviation, it looks like TMFR, TBFR or TBFM?

I do not know if it is a color TV experimental. is in fact a console version. the group sintony not present in the facade could be side

What country was the scientific journal article from? This could very well be a non-US set, making guessing all the more difficult.

the photo is taken from an encyclopedia of the 70s.
i do not think that is european tv set.

you are right. there are 4 letters,

the first is not identified _
the second seems an E
the third seems an A or C
the 4th seems a M or H

- E A M perhaps TEAM ? or TECH???? or BEAM?

in attach one pics magnified

I'm still fascinated by the monitor in the background. It looks like it uses the CBS H266 rectangular tube from 1957:

Westinghouse and CBS made TV sets using this tube. The Westinghouse version is shown here (toward the bottom of the page):

http://www.earlytelevision.org/21_inch_color.html

What vintage is that scope and when did what I call "camera bars" (non-SMPTE) appear?

If that monitor is close enough behind to cast its reflection on the piece of equipment the man is looking at, it doesn't look like the screen would be big enough to be an H266 as it's definitely smaller than the 21" round CRTs.

That picture was probably retouched quite a bit.

David, I'm not so sure. It looks like it is some distance behind, and the screen could be 21".

If you are right, what tube do you think it uses?

ok ok! but that brand are those in the foreground? through the help of mr fixer something is beginning to understand but none of the names discovered seems to exist, howevwer in 1954 Zenith made a Rectangular CRT

I was thinking, the only American electronics company that has a 4 letter name is Dage, I once had a industrial video camera made by them. They still are in business. Here is their history page on their website.

If it is an American, it made might be by them.
I found a page on early television dot org , on dage monitors and history. they never made tv sets just monitors and cameras
http://www.earlytelevision.org/dage_650.html
Actually i found another American company that uses 4 letters GRAY research
here is a link on them
http://www.earlytelevision.org/gray_monitor.html Logan

thanks you very much for the research, but the two names suggested by you do not seem to have made a similar model. in a moment I had come to mind BARCO a factory of belgium that produced precisely minitor professional, but with wooden furniture as for color TV consumer. But BARCO it is 5 letters, no 4. and then I think that in the era BARCO did not exist yet. To that time there was the BUSH, PYE and Philips that began to produce color TV manufacturing, is perhaps the English, and perhaps really BUSH?

I think full field bars were one of the earliest electronically generated test patterns, so I'd say they go back to the 50's. I know before SMPTE bars there were RCA bars which were different. I only had one machine, an old Telemation from the 60's that generated that type of bars, but they were also electronically generated. I think earlier than that and you're talking slides and camera cards for the test patterns, since the monoscopes were only suitable for b&w. Although, I suppose you could theoretically use a 3 tube monoscope to generate a color pattern, but I don't think I've ever seen one.

David

Which encyclopedia (brand and year) and what article?

The Scope is late 50's early 60's. Tektronix.

Two electronics companies come to mind that may fit your four letter logo , starting with "T". "TERK" made video monitors and I believe "TEAC" also made/makes video monitors.

-Steve D.

TERK uhhmmm ... IT is American company? TEAC instead should be Japanese, I would not understand that TEAC has produced color monitors in those years. they were more in the manufacture audio equipment. now a little navigate the web and see if there is material with the initials approached me cite.
Yes the vaweform it is TEKTRONIX is recognizable by the red knobs.
the photo belongs to a printed encyclopedia (1973) in Italy and the article spoke about the birth of colour TV. There were other photo cameras with 41 TK and TK 42. I public below

My first thought is that this is not Zenith - I don't believe they ever had any chassis like the round tube ones, and their early rectangular tube would have been used in a large floor model cabinet that contained a girder-system mechanical chassis for easy modification they used for their experimental 15GP22 inch sets, I think. The one in back seems to be a monitor rather than a developmental chassis - very interesting, but hard to say for sure. The indian headress boy slide was one we had at Zenith, but right now I can't recall what the source of the slide was. It is not one of the original Kodak NTSC test series. I don't recogniz the flower slide. An amazing thing about this picture is that it appears to be of real TV pictures, not mechanical cut and paste. Note that you can see a shadow of the bezel on the flower picture, and both pictures have the proper perspective distortion for the angle of the sets. This has to be a carefully lighted and exposed shot by a photographer who was used to making such pictures for publicity and advertising.

This is the kind of picture that could have been shot originally for inclusion in an annual report of a company.

Please tell us the name of the journal and post copies of the whole article if you can.

Another thought - this lab apparently had two simultaneous sources of video! You would not find that at Zenith or Motorola, I believe, only a really rich place like Philips or some place associated also with broadcast equipment.

Also, I don't recognize the piece of test gear the man is touching.

Could this be French or Canadian?

AHA! I think the badge says SECAM!

EDIT: I looked again and I'm not so sure

uuhmm .. is really difficult, I believed that it was easier to identify which brands were 2 color TV SET. on label you read SECAM? uuhhnn no there are only 4 letters I, for example, now a coup eye we read SEAM. images are extracted from a book for children called "Tell me how it works." In language original; "Dis, comment ca marche" Translate in italian "Dimmi come funziona" I found the book, and I went to see the press. is the library Hachette Paris years 1972 and all authors of the book are French, then you might think that the photo is taken by a French laboratory. In attach some new picture

I found a paper on the business and political history of the development of SECAM, PAL etc.
http://www.h-net.org/~business/bhcwe...0062-p0068.pdf

It says that initially there were 40 French manufacturers of black and white TVs, but that the expense of developing SECAM eventually resulted in many mergers until there were only 2. None of the steps mentioned along the way would have the initials SEAM, so it is still a mystery.

The cooling vents on the top look very Philips/Normende. Like the vents on the European radios from the 50's/60's.

The rectangular set has a very European style. My guess is that the round sets are partially RCA (crt and maybe the basic cabinet) with a chassis pieced together by someone in Europe. Could this have been a comparison of different systems for color?

The whole thing looks VERY "staged", to me. And the pics on the CRTs are almost certainly "matted" in. Still, it would be nice to know who/what/when, wouldn't it ?

Thank you: old TV nut, Dave A, bgadov and Sandy G for information and research, look what I found on another magazine that was published in May 1976 in Italy and spoke of the imminent start of color TV. The same image of boys dressed by Indian and surrounded by toys. the same that we find on the second TV SET brand still unidentified. There seems strange? Who was the institution which used this type of image as the pattern for color TV SET distance of many years?
Dear old TV nut, even in Italy at the beginning there were many industries tv, then with the advent of color PAL, are all missing, or acquired by other big brands. phenomenon that I mentioned in a special chapter on the advent of color TV in Italy in my thesis at the University.

This picture was a test slide that was widely used - I just can't remember if we had a copy at Zenith, or perhaps I saw it at CBS Labs while I was at Motorola.

Regarding "matting" of the pictures - they are not matted, which fact can be seen by the correct perspective and the shadow of the lighting on the foreground set's face. However, these sorts of photos were typically dione by double exposure. First the scene would be photographed with the lights on and the people in place, but the TV sets turned off, with filtration for incandescent light. Then all the lights would be turned off and the TV pictures exposed with whatever color filtration was needed to match the phosphors and white point to the film. (With most film formulas, the sensitivity to the red phosphor was not very good, plus most home sets were set to a very blue color temperature.) It is also likely that a slow shutter speed was used, thus the pose of the man with all parts of his body touching something to keep him stationary.

The slide is called Boy with Toys and is a pretty common slide for flesh tone and color. I think the BBC originally developed it, although I don't know that for sure. I know it used to be a pretty common one. I once upon a time had a camera card of it that I would use to line up studio cameras so that they all matched in color.

David

then could be a British laboratory and the brand of TV SET yet unidentified could be manufactured in England. could be a good clue. fernando

Yes, I remember the name "boy with toys." Still can't recall how I know that. The EVR project that Motorola had in cooperation with CBS Labs also involved a British firm that was set up to make the film cartridges - so I could have seen it there.

http://www.labguysworld.com/Motorola_EVR.htm

also nordmende in the'70s had produced a device to see 8mm films on television. I do not know if it was a thing of their manufacturing, the fact remains that you can not know what brand are the two colour TV SET

Hi firenzeprima,

I believe the photos were taken from the experimental period of PAL color television in 1963 to 1966. Here are some photos for comparison.

Blaupunkt1966.jpg shows the front of a color tv documentation (note the round screen!)

ExperimentalColorTVlaboratoryWDR.jpg shows the color television laboratory of the West German Broadcasting Corporation (WDR) in Cologne.

UniversityHanover1966.jpg shows a PAL color television demonstration in the Engineering School of Hanover.

Kind regards,
Eckhard

Hi yagosaga,
what you told me is very interesting, as for the photos that you have attached to me, I believe that the last is a kind of history by the development of colour TV, from experiments to the TV SET for the market. you you have the other to be published?
Note that the photo of "child with toys" is reverse compared to those that I have. So here there is a triangulation between France, Germany and England with regard to TV SET to be identified,,,
thanks for the information! Fernando

The scope looks like an HP from the early 1960s. Both EIA and split field bars are available from the Tektronix R146 Generator, probably 1969 or maybe earlier.

I sent the photo to Marcel van Grinsven of marcelstvmuseum.com. He replied;

"I have never seen this color tv in The Netherlands, only the 21KX100A. I have two 21KX100A color tv's.
On the background a monitor with the Philips logo. See the picture.

Perhaps french Philips, france use the SECAM color system. The Netherlands use the PAL color system.
Philips has worldwide factories where tv's were made, in Europe: The Netherlands, Germany, France, Sweden and United Kingdom.
In the sixties sold Philips only for the local market. The countries had several tv systems.

Best regards,
Marcel van Grinsven."

There is a logo and script in the lower left of the rear color monitor. He may be right on the Philips.
