polaraman,
I concur wholeheartedly with the comments on your latest find. Those older Zenith TVs are great; I've had a few of them in my time, and now collect small Zenith radios (I have one from '51 in my bedroom and a very nice walnut-cabinet AM/FM from '63 atop the refrigerator in my apartment, which both work--and well).
I did not realize, however, that the set you have was the first Zenith chassis to use an IC as the chroma demodulator. I don't know offhand what vintage that set is, but seeing that it has a UHF tuner it must have been made after April 30, 1964. However, as to the chroma IC, I think this was Zenith's answer to RCA's first use of an IC in its sets in the audio circuit, or perhaps it was the other way around, depending entirely on the vintage of your Zenith (RCA introduced the IC-based audio system in one of its small portables in 1966).
