1979 and 1980 Zenith 19" color sets

[DavGoodlin]

I feel fortunate to have worked in 2 shops that serviced many 19" Zenith models back in the day.
The weight difference from a system 3 is probably significant. The CCII sets had the regulating transformer and seemed even heavier than the 19" XL's and Colortraks (to a tall-skinny 18 YO at least)
