1976: 19” Zenith Chromacolor II (chassis 19HC48)

This may be completely normal and you are just looking for a cleaner response than is possible when the signal goes through an IF filter with its necessary sound traps.

Check with ordinary program material and see if there is anything terribly objectionable.

People's memories of how analog TV looked have faded these days when they have gotten used to HDTV and computer monitors.

Edit: besides sound traps, the color subcarrier trap can cause some luminance ringing, depending on its bandwidth. Wider bandwidth = less rigning but more smear, and vice-versa - it's a design choice that was made for regular program material, not games or test patterns.

I don’t have this ringing distortion on my 1967 Magnavox T931, which is a fully tube VHF, IF, luma, and chroma demod chassis. So I am confident I can get less luma distortion on a solid state chassis. I know it isn’t going to look like an HDTV.

Aside from this ringing distortion, everything else about this Chromacolor II is stellar! The dot pitch and the focus are better than all of my other consumer SDTVs from the 1960s through 2000s. Why did TVs take a step backwards from the Chromacolor II’s dot pitch? Even Zenith seems to have taken a step backwards after the Chromacolor II.
