You like the CTC16 chassis. Do their flybacks normally run a tad on the warm to almost hot side?

Warm to the touch. I use the back of my finger to test. I can hold my finger there for as long as I want, not hot.... Too hot, and you've got any of the problems I mentioned in the other thread.
Only RCA flys that ran hot were in some of the 19" tube portables - the pulse regulator sets, as we called them. The load vs size got them hot, but I can't recall one ever failing. We used one as a loaner and the only problems were usually related to the 5GH8s. Too unreliable to sell, so we kept 'em for loaner sets.
I like all RCA color sets, up to the CTC175, and any with a MST/MSC module....
The CTC16 was RCAs largest-selling tube sets, with the exception of the CTC38 (another flyback eater, 119834), IIRC. The 16 was extended in the CTC16X, so those numbers were thrown in too.
Somewhere in Google books is a book about Japanese dumping, and the EIA production numbers for domestic sets from 1964 to 1970, by brand, is listed. RCA creamed the competition in the mid-60s, but Zenith and others caught them by 1970, through initial quality and features. We sold and serviced RCA until 81, then it was just servicing. Mass merchandisers were selling sets cheaper than we could get them from RCA, but we didn't buy entire railroad carloads at a time either....
Back to the flybacks - read the service clinic articles in Radio Electronics and Electronics World magazines - authors such as Jack Darr, Art Margolis, Carl Babcoke, and Homer Davidson - these guys were servicers that got to write about it, and dogged many a chassis to find the unlikely culprit. But Darr and others also wrote about prevention of problems (callback avoidance) and how to get a set healthy for the long haul. Not too many specifics, but enough generalities to get a sense of what to check....all of their stuff is over on AmericanRadioHistory - the search engine is wonky, so try different combinations to find what you are looking for. Oh, and the January Issue of Radio Electronics in the 60s generally was their "Color TV" issue, with more articles on Color TV than the rest of the year's issues....
