RCA, CTC-10A, Metal Cabinet Roundie Color

[BigDavesTV]

I’ve paused (for now, after getting this RCA, CTC-10A basically working, this week. It is model: 211CB822, "The Sullivan" in a metal, gloss black lacquered cabinet. I won this set in the Silent Auction at the May 2015 Early Television Museum Convention Meet. BTW, for any of you that have yet to attend your first time there, if you have the chance, you’ll really have a great time! This set has provision for screw-on legs, which I believe were gold-colored, metal. The legs are missing on this set. I plan to fabricate some legs, eventually, unless someone has a set of legs they don’t want! These pictures were taken with the set sitting on my lift table cart, just after re-assembly. I am pleased to have it working, albeit basically, at this point. The CRT (21CYP22A, originally), was replaced with an RCA HI-LITE, 21FBP/GUP22A, and 2nd. Anode Conversion kit, at some point in its life, as the date code on the replacement tube is '68. This (replacement) CRT, tests quite well, not as new, but certainly usable. I still have to do some work on the focus circuit, the poor focus is a little better than these pictures show, but it had the same soft focus on my Sylvania CK-3000 Test Rig, which normally focuses well. More to follow, later, after I buy the proper resistors for the focus circuit, and a NOS 1V2. To get this set working to this point, all electrolytic capacitors were replaced, and then the Horiz. Osc. / AFC board needed some new capacitors, and a few drifted value resistors changed, in order to get proper horiz. osc. drive to the 6DQ5 HOT. Next, came some caps and a few resistors in the Vertical osc. and output (6EM7) section. I think the vertical could still be a touch better, but it’s way better than when I started. The original 3.58 color osc. crystal that looks like a 9-pin miniature tube, is still working and stable, so far. I have recently worked on a couple sets that were 8 or 9 years newer than this RCA, that had a bad 3.58 crystal. This TV was manufactured (at least a couple chassis parts were) in March of 1960, just a short time before I was born in June of 1960! So I really wanted to get this set going, since it was new when I was a baby. I also really like the shiny black original cabinet with, (it’s few nicks, scratches, etc.,.. hey…it’s “patina”). More to the story later on , as with most old sets, they are a “work in progress” as time and resources permit. I hope you enjoy the little photo tour!
