My Newest Addition RCA CTC9 Caulfield 1959
 
Yesterday I picked up a RCA roundie color CTC9, Model 210CK924 Caulfied. Yes, I gave $200, but it looks like it was well worth it, as it is in prestine condition. It was previously owned by the grandfather of the family I bought it from who was in the TV repair business. I understand it was his pride and joy and now it's my pride and joy. Thing is, nearly everything in it is original including the 21CYP22 CRT which checks .85 on all three guns on my Beltron. The flyback is original, but only a few drops of wax present from it which is basically normal for those. Most of the tubes are original RCA. Brought it up slowly on a variac, and electrolytic cans seem to run cool so gradually put full line voltage to it. I hadn't even removed the chassis, roughly adjusted the screens and drive, so figured I'd try it out and put on a DVD, and guess what, color looks fairly normal, full height and width. I was told that the set had sat idle for 8 years without being turned on, but with a few tweeks and adjustments it produces a very nice picture for a set of that age. The cabinet is a light maple and is almost as good as the day it was purchased. What do you guys think it should do to it, to keep it running like it is or even better. I am afraid to pull the chassis, as I don't want to mess anything up or break anything. I plan on accurately setting the grey scale, convergence, and checking the HV, etc. The 6BK4 HV regulator tube looks kinda dark, but don't know if thats a problem or not. I plan to post some pictures of it on here, but not sure how to do it, or if I can. Guess I'm so excited about this find, that I couldn't wait to post it on here.

CTC-9's working great as found is pretty normal, mine worked with good color straight away too. I recommend changing out the power supply caps just to be on the safe side, if those take out the power transformer you'll be in a hurt locker to find a new one. 6BK4's get dark glass from x-ray exposure, it's normal. I've seen them completely black before, but still have decent emissions.

CTC10 built into the wall of a house on 143rd and Newport ave. last summer I PASSED.(!!) It worked like you say with a slightly reduced vert and dim color.
He wanted 100$ and I was to remove it from its resting spot.
I know for a fact the house was demolished in the hurricane. What a shame.

Great story on your '9 though..

I have the same exact set as yours but mine has a million hours on it and is still working great with the original fly but cant say that about the crt, It's been replaced at least 6 times,

Great looking set. Looks like the same wood as my CTC 10 but different cabinet style. Great score. Don's trust the electrolytic s tho. Mine were good but after a year they died. Recap for sure.

The PC boards must be like burnt toast by now. It is a beautiful set, though. I like the cabinet style.

Here are some pictures of the RCA CTC9 Caulfield Set performs very well. I had to replace the 12BY7 video output tube, as it was leaky, and as the tube got hot the brightness control would not work. Also adjusted the HV to 23.5KV and set the convergence as close as I could get it. Electrolytic cans run cool (at least for now), but I'm sure I will be replacing the caps in the future. Flyback only has a few drips of wax, so it seems to me that the set has not had much usage through it's life.

mstaton 07-20-2013 09:54 PM

Yes one of the boards is black as coal. My original electrolytics are still good

Very nice looking set. I've got a metal cabinet CTC9 with the wood stand, which is cool looking as well. Nice score!

tvcollector 07-20-2013 10:31 PM

Nice set... I'm getting a set in that same exact cabinet.. It's a CTC10E and is a remote set..

RCA Caufield
 
Drool, drool. Wow. Only thing missing is the hang tag and the retail receipt. What a beee-u-ti-ful set !!! Hearty congrats!

Is that the original CRT? I also noticed no cataract. Is there a seperate safety glass with these models, or a bonded glass? Fantastic.

Please post pics of the set in operation, ( I know you will, when the time is right) but as others have suggested, not without replacing the filter caps.

Oh, my bad! In the first read, I missed the part about the 21CY CRT being original.

Even more wow!

walterbeers 07-22-2013 03:39 PM

Yes, It has a separate safety glass, which is removable, so hence no cataract. And yes, it's the original CRT, even has the serial number sticker on the CRT. It seems a little dull, but gosh, for that age, it's not bad at all. Checks around .8 on my Beltron on all three guns. I will try and post a picture of the set in operation soon.

It's been quite a while since I spent any real time with this set, as it had developed a problem with the vertical slowly collapsing, and loosing sync. I've been busy working on other stuff including my RCA 21CT55, so it sort of got shoved aside. Well I got back into it, and the problem with the sync and vertical collapsing, was just a simple problem. A ground on the corner of the circuit board that connected to the 6CG7/6FQ7 (vertical osc and sync) which went to one side of the filament pins. Re-soldered it, and it's back to normal. CRT is actually getting better with some use, it now checks over .9 on all three guns on my Beltron. Original 21CYP22 still going strong. I believe it is really a low hours set. I never run any of these old tube TVs unattended so if something should go bad (IE filter cans or flyback), at least I would be able to disconnect it right away, rather that leaving it on causing more damage. Filter cans right now run cool so I have left them alone for now. Here are a few more pictures of the set.

Well, you fulfilled this promise 1,110 days later :D

kvflyer 08-05-2016 04:56 PM

And (unfortunately) that very problem has come up so many times. I just hope that when I get into my color tube sets (soon) that I remember this problem. It is often a simple problem and I often look for some major issue... that doesn't exist.

BTW, thanks for sharing it with us!

How is the CTC 9's color reproduction compared to the 21CT55?

jstout66 08-08-2016 08:23 AM

I haven't seen the sets in operation side by side, but the color is more vivid on the CTC-2 and the picture is sharper. The 9 looks good, but the picture is softer, and the colors not as vivid. Walter?

I will try to find a splitter and and post a picture of both of them working using the same picture on both. The 21CT55 seems to pick up a lot of interference when I use channel 4 for some reason here at my house. Channel 3 produces a clear picture. Generally the 21CT55 seems to have a sharper picture, with more vivid color than the CTC9. Both CRTs test over .9 on all three guns on my Beltron checker. Time for me to head for work, will see what I can do as far as posting this afternoon.

Nice set, Walter!

radiomec 09-09-2016 03:52 PM
