My new CTC-11!

Just picked this up from a seller on Craigslist in Hillbillyville, TN. Paid $100 for it. Numbers matching CRT. Haven't tested it yet, but the cathodes don't look too burned. I had to take it apart on the spot to get it in the car.

Yep. You really can't appreciate how BIG this thing is until you get right next to it. This thing absolutely dwarfs my Zenith 25CC50 table model. And it's a 25"!

No! Where there's a will, there's relatives!
I hauled one of those in the trunk of my '64 Valiant. Naturally, the trunk was up. I wrapped a moving blanket around it and tied the trunk, so it wouldn't bounce up and down.

Happy for you! I have one exactly like that waiting for repair/restoration. RCA must have made many of those in black. Hope your CRT tests like new!

Still on the road home. When I get it unloaded, expect many more pix.

The CRT is good! I had to use the Auto Restore on the CR70, and it responded extremely well. The base broke though.

Here's how the CRT tests on my newly repaired B+K 470. This way you can see all three guns at the same time. I also tried my B&K 445, and there must be something wrong with that tester, because it tested very weak. This tube has the old school sulfide phosphor too, that's pretty cool.

Good score, U.D.! That chassis is clean, not tarnished or rusty, and the Yoke plastic housing is still white! These make excellent pictures, with a restoration! Nice to see in the black lacquer metal cabinet, I have a CTC-10A in the same cabinet. I like to test crt's with my B&K also, to see all three guns at once, but I do not recommend using the B&K to do rejuvinations, as the Sencore CR-70 is much more gentle and gradual, especially the Auto-Restore. This is my own experienced opinion, after trials and errors in the past!

I forgot to mention, the roundie in my Avatar picture, is an RCA, CTC-11, that I restored, and used to own, now another collector friend of mine owns it!

Great set you got there, and the only RCA I would recommend to a beginner for restoring. These RCA's did not suffer the heat issues later sets did either.

I have the "Covington" in mahogany print on metal, which I believe yours is also. A fellow VK member traded me mine for a Zenith roundie. The model number on yours would be one number off for the black finish, 212-G-802 MV, 2=ebony. Not at all surprised on the CRT coming up like it did.

Dave- yours looks like it has UHF too. I never saw a CTC11 with the UHF tuner.

Nope, no UHF here. Or high voltage, or horizontal oscillation. On the way home, a coil right next to the 6FQ7 horizontal oscillator broke, and the teeny tiny lead got ripped off. I don't really think that one little coil would kill the high voltage and horizontal oscillation though. I might be replacing the flyback...

Edit - I must be super tired or sumpthin, I realized that if the horizontal oscillator coil is broke, it will kill the HV and horizontal oscillator. DUH...

I can't clearly see in your picture where that wire is broken, but if it's right where it solders to the terminal it should be possible to carefully tin the coil wire and bridge the gap with another short strand of fine wire. Or did the whole coil form break off above the pc board?

There's a handy little trick for stripping hair-fine wires that doesn't involve abrading. It may be useful more often than you'd think. Scroll down to post# 26 -
