New to VK, here's my CTC-11 I just aquired
 

Greetings VK, newbie here so be nice! I figured I should join this group as I now own a CTC-11 ‘Roundy’! I grew up with a CTC-15 my parents purchased in 63 or 64, just after I was born. The CTC-15 had a factory remote which I still have, and with minimal service the set ran into the late 80’s. It suffered from the typical cataract which is why it was retired from daily use. Shortly after it was put in storage a shelving unit collapsed and broke its CRT and at that time it was regretfully disposed of. The set served my family well and I miss it!

Problem solved. In consulting with VK member Phil N., he suggested I be patient and something will turn up. It did, a CTC-11C (212 G 866 MV), although I cannot find any printed advertizing, nor do I know its cabinet name. It was in a part of Minneapolis about 30 minutes from my residence which was a bonus to me! I’m excited to own it, I’ve got many years of radio and B&W TV rebuilds under my belt and this will be my first Color rebuild. Phil and his site have provided me a great knowledge base. I know in reading there are things to watch for in various sets (ground lugs), but I’m not sure what specifically with the CTC-11 series of sets. Lytics, maroon-drops, selenium stacks, and out of tolerance resistors are at the top of my list of things to start with. Any other hints would be welcome!

Attached are pictures of my set prior to clean up or inspection. Inspection revealed a thick blanket of dust, no picture-tube brighteners thank goodness, and no obvious problems (yet)… My next step will be chassis removal, cleaning, and an inventory of capacitors/out of tolerance resistors. More pictures to follow and I’m sure a plethora of questions once it’s time to bring some voltage back to this set. Thanks for your support and I look forward to communicating my progress.

nice looking set, welcome to VK

You lucky dawg !! Noob, & already have a desirable set ! Congrats, & BTW, Ah HATE Yew !! (grin)

Welcome to Videokarma. Please keep us updated on the progress of this set...

Don't mind sandy he "hates every one equally".

I'd replace all lytics and paper caps ,but leave the orange drops (which aint always orange) alone.
Should work alright after that and some adjustments.

I used to shotgun all orange drops in a stage that was missbehaving after said preliminary recaping, but now that I have a working eye type cap tester I only remove the ones that test bad.

I love my two roundys, and bet that you will love yours too when you get it going. I wish you good luck in your restoration.

Welcome to VK!

Welcome Bill!

Welcome to you and your new baby.

Nice score. That cabinet's in great shape. Let's hope the innards are just as solid.

I think my two CTC-11 articles say all I know about that model. If you get stuck, there are people in this forum who know much more.

Enjoy!

CTC-11 would have silicon rectifiers, so you're good there. I bet it'll run just fine after replacing the power supply filters, and checking the horizontal and vertical circuits for any wax caps/black beauties that might have been installed. I had a CTC-9 that worked on all original parts, so anything is possible.

Welcome. That's a very nice 11 you have there. Looks like you have a non-bonded (separate from the CRT) safety glass in that set. That sure simplifies things. My 11 still works with its original caps, but I don't recommend that practice if you intend to watch it much. Best of luck with getting yours going.

Hey Bill,

Welcome to VK. Your CTC-11C model 212G866MV is called "The Brookfield." Very nice upright console.

oh I wish u luck mate ... we poor aussies never see ... let alone own a roundie!

Then perhaps it is time to import one.

Whilst colour was a late coming in Australia for us to have roundie sets, there are a few roundies kickin about over here. There's a roundie monitor at Powerhouse museum and my mate John (who has the largest vintage TV collection in Oz http://cool386.tripod.com/ ) knows of a bloke down in Melbourne who has a 1960s roundie colour TV imported for experimental or training purposes.

Thanks for the link

Bill,
Welcome to VK. There is no shortage of wisdom and support here on these wonderful sets!
That sure is a sweet one! I have the blond version of that set model 212G837MV. It was named the "Wakely".
A quarter century ago I worked for a Zenith store in Allentown. I rescued one just like yours that was traded by a little old lady (for a new System3) who barely used it. We had it in the bedroom of our apartment in case there were two things on cable we wanted to see.
I could not take it when I moved....the rest is history.

One of my big regrets to let that go, then in '86, I got a second chance. I will keep this one forever!!! I also have a CTC12 in a blonde french provincial cabinet, named the "Burgoyne", it even has a UHF tuner, but needs restored.

I have a CTC 11 21CD435 What is the name of this one ???

Possibly you have a 211CD435, as I don't see a CTC 11 model 21CD435 listed?

Anyhow, the 211CD435 doesn't have a name attached to it in the RCA field service guide. There apparently were a whole bunch of sets that didn't get names. I'm not sure what the story is on these.

Kevin, Thanks for the response.. I see My cabinet on the forums, it goes to the floor - no legs. It has the New Vista - Color but a differant fram around the Tube with dark gray safety glass. Did they have a early-late 1962 units ?
Do You have a user manual ?

Hey welcome to VK! Great people here, never met a nicer bunch. Thats a beautiful 11 you have. That CRT is clean too!

All I have is the 1955-1966 Field Service Guide. That covers the CTC-2 through CTC-20 service info. But there’s not really any model number-dating info in it. I'm assuming most 11's were made in 1961, but I'm not sure. Possibly the serial numbers have encrypted date code, but I've never heard of anyone explaining the numbering system.

I believe the RCA CTC-11 was produced for the 1962 model year. Most models had the 21FJ bonded safety glass tube and others had the 21FB separate safety glass. Both had the newly introduced all-sulphide tube. This may explain the difference in the masks.
The numbers contain info on model type, cabinet finish & style, additional features, chassis production changes, date codes, some info for the bean counters and on & on.

-Steve D,

Thanks, Steve.

Is it possible a new model year was available for sales before the actual first of the new year?

Hey Kevin,

Like new cars, new model tv's were available, usually, in the fall of the previous year. Sometimes even earlier. The model year for the CTC-11 may have been from late 1961 to late 1962 when the CTC-12 models were introduced. The marketing dept. would plan new model intros. in time for the Christmas season. Or place new model year RCA tie-in ads for NBC color specials or the World Series ect. Also, slow moving models may be dropped from production and new models come on line anytime. RCA also had lots of unsold CTC-10's in dealer's inventory, so the timing of introduction of new models was tricky. Selling color sets in the 50's & early 60's was risky business.

-Steve D.

Interesting.

I had a conversation with an older fellow who insisted he'd bought a CTC-10 set for his mom during Christmas leave from the service, 1958. I assured him it could not have happened that way (that went over well). Anyhow, I'd have to guess his remembrance was off by one year. My experience has been that most people do tend to error a few years further back than actual.

A year or more, if model years overlapped it's possible the CTC-10 came out later in the same year as my CTC-9 ('59).
