Well, ya gotta remember that those RCA cameras were designed and built with 1954 era technology. I remember when I was in school in the 1960's we went on a field trip to NBC "Color City" in Burbank in 1968 and I remember the lady telling us that they were still using mostly all 1954 equipment.
CBS on the other hand had those Norelco color cameras using 1965 technology and the result of more solid state innerds was that the color had that pastel look that either we love or hate. An easier to use more modern design but the richness of color wasn't there. Those RCA cameras really had their purple down pat!
Heck, I remember when I was working an a temp at NBC, Burbank in 1977 they STILL were using all of that old equipment from the early 1950's. I guess somewhere down the line they shit-canned it all but they kept it working for almost 25 years...The monitors in the main control room (with that giant glass panel to look through) still had their 21" roundie monitors in the 1970's as well. One was labeled "To Transmitter" and the other set was labeled "On Air". How cool was that, eh?
