Help identifying RCA XL-100

[jbattles]

Those were goods sets 1977 is about right. The 1976 models had the trace and retrace scr horizontal section. Which was a pain to fix and weighted as much of a Cadillac from 1976. 1977,1978 and 1979 all had different chassis. I think 77 was modular and was 78 and by 79 there no modules. RCA and Zenith were the top 2 made in us sets i miss them days.
