Rca Ctc-11

Hello, I'm new to this board so I'm still learning. I have an RCA CTC-11 that has worked well for years with small fixes (replace a tube here and there). Now It's starting to need some caps, etc. And I'd like to replace the flyback. There are some very knowledgable folks here. So if anybody has any service information about the CTC-11 or a source of parts that would really help. Also, any troubleshooting pointers would be great. For a long time it has needed about 15 minutes to get up to full brightness. Any thoughts?

Thanks, Dave

Could be the HV rectifier is getting tired, or possibly even the picture tube. Weak video output tube might also cause that. I've never worked on a color set, so there might be other issues. Bad caps are to blame for a lot of things, and if this particular unit uses a voltage doubler arrangement for B+, bad caps in that circuit could cause weak B+.

I'm told that Moyer Electronics is the place to go for flybacks and other oddball parts. http://www.moyerelectronics.com/

I think I've found how to attach pictures. Here's one I just took. Not too good, but you can see it anyway.

That is a very cool set! By the way, is that a console in the bottom left corner of your photo?

I remember being a small child (in the 80's) and remember my grandpartents had what i now can identify simply as a zenith roundie. I remember thinking it was way cooler than my parents TV. I dont recall much about it. Ill ask my grandfather what ever happened to it.

Grandfolks ALWAYS have the COOLER stuff! Mine had color in the '60's whereas I had to buy my OWN color set in the 80's!

My grandmother used to give me some cool radios she'd find at garage sales. But my uncle and his father-in-law were both into radio and TV repair. Back in '71 when I was about 15 they were cleaning out their basements on two different occasions and I was invited to take anything I wanted. I took a friend with me and we were both just in hog heaven. As my uncle's father-in-law repaired radios and TV's professionally in the 50's and 60's I remember a LARGE number of old color sets sitting around in HIS basement (like these CTC-11's). But we both went for the radios and related parts as they were more within our (limited) scope of repair ability at the time.

Wow! That is a nice looking set. I don't get to see many 11s.

It looks like you either have a weak green gun in your crt or your grey scale adjustment is way off for starters. Nice looking set though and overall looks like its playing decently. It wouldnt take too much to get this one playing like the others on the forum here.

Don't listen to 'em. Yr TV is JUNQUE, about ready to die. It CANNOT be fixed, as that particular model is COMPLETELY made up of Unobtanium parts. Yr best bet would be to ship it to me, prepaid, of course, & I will give it a good decent Christian burial....(Mbwahahahahaha...Maybe THIS will be the one who believes me....)-Unca Sandy, Under the Bridge, Hawkins Co.

When it takes time to get a good picture or brightness, most likely your picture tube (CRT) is weak. A simple setup may make it look better but a weak CRT is what you probably have. What makes you think it needs a flyback or want to replace it? Flyback looks like it is doing its' job to me.

Thanks for all the responses. The Flyback has some "melting" and some HV leaking when the screen goes from light to dark or when I turn down the brightness control. Actually I think all the guns are good--that picture just had too much red in it because of what happened to be on the screen at that moment. I just figured that replacing the flyback would be a good thing. But mostly I need to replace some caps on the vertical board and I figured I should do other stuff while I can. Here's a better screen shot. Thanks again for everyone's help.

Welcome to the CTC-11 club! Here's some pics of mine. I think it's pretty common to see some melting at the flyback.

Nice screenshots! And I like seeing a tube Fisher on top of an old RCA set. Perfect combo.
