I like the CTC-121 with the flip-up metal door atop and stereo speakers and on-screen-display.Those sets had a huge remote control and composite video inputs too. A neighbor has one and I always ask for it

..In the interest of not getting side-tracked here, I will comment on the early color tubes.
I'll tell ya, I'd be more interested in finding some of the RCA studio gear from that time--the "mil-spec" color tube-chassis monitors to do air-checks, and stuff like that. Where are all of those monitors from the '50s? One can only imagine..
I applaud the extensive efforts being made to restore 1950s color TVs.. I cannot say i have ever worked on one.(or ever seen any)

I have one: an RCA TM-10 using a 15GP22. Restoration is underway, but this is not a trivial project (for me, anyway), so it's taking a while.

Also, let's not forget it was just about the only set besides the CT-100 to have full I/Q color demodulation. I have one and the picture difference is very noticeable, especially with pastel colors.

I worked on the CTC-131 and it was the first to have full wide I. The CTC-121 appeared a year earlier but was not wide I. The CTC-131 also has an auto kine bias set up. Which does track low lights over time.

Doesn't the CTC-133 also have full I bandwidth?
