Ctc ??

[Kalamazoo-DJ]

Here are some pictures of the CTC , it works very well but again not sure what model it is. It also has UHF, does anyone have an idea of what model it is? It says 1958 on a tag in it. If you need chasis pics I can get some.

There's no chassis stamp with the number on it or it's missing?? Yeah, a back shot may be handy. That would be rare to have a UHF option!

[marty59]

Okay, I'm 'gonna say a CTC-7 and it has 5U4's mounted on the P/S Transformer and a 21CYP22 CRT.

In the 1950s it was rare to see a TV with UHF, as most older cities did not have UHF stations until the '60s. My best guess, however, is that these late '50s sets with UHF tuners sold very well in UHF-only markets such as Scranton, Pennsylvania, Youngstown, Ohio, Fort Wayne, Indiana, Fresno, California, et al. If the sets lasted long enough and were located in markets with VHF stations but no UHF ones (at the time the set was purchased), the sets would be ready (no need for a converter) when UHF stations arrived in these areas.

Interesting now with DTV, I think I might be able to pick up 16,22,28,41,46 one station out of Battle Creek MI and four stations from South Bend IN but with Direct TV I never tried it since I crashed the antenna to the gound to get it off the roof.

Remember, that while digital stations in your area may be transmitting on UHF frequencies that you can "tune" with the UHF tuner in your set, you will see nothing more than increased "snow" when you tune these channels. An analog (NTSC) TV by itself cannot decode the Digital (ATSC) data that is being transmitted.

For Kalamazoo, the FCC lists two analog stations (WUHO Ch 36 and WOKZ Ch 50) that your UHF set might be able to receive off the air, without a digital converter box:

ok thanks, that is WOTV/Wood weather doppler radar map I think or maybe that christian station hmmm I didnt think they did much change in UHF around here.WUHQ used to be 41 then wotv/wood got it last

I'm from and currently live in the Scranton-Wilkes Barre area, and the only VHF station that we had was W07BV, which was a low power EWTN affiliate, and I don't believe is broadcasting anymore. Our NBC and CBS affiliate broadcast on RF channels 13 and 11 now, but before the analog switchover it was all UHF except for W07BV which is on channel 7.

And the goop is putty-like in consistency, leaking out of the same hole that the wires come out of on the power transformer. It's not really "leaking" but seeping out ever so slowly. Some of it is running down the safety glass, and takes days for it to move a half an inch. It seeped out because the chassis was horizontal, not vertical. It's a tan color. I have no idea what could remove it. The power transformer still works fine. I can't peel it off because it's very sticky, and like a putty.

I don't know exactly when they started using Mylar caps. Anyhow, you might want to check a couple of those maroon guys before you shotgun all of 'em.

RCA parts list says they are indeed paper. I thought they were ceramic until I cracked one open. They look like paper with the silver foil. Since audio worked on the chassis, I'm willing to bet a lot of them are still good. I doubt they are mylar. Attached is a few pictures of one broken open, though a bit blurry.

here are some chasis shots very dark but the best a phone cam can do, I found ctc 9 possibly but it is double stamped smeared and too hard to read.
shows uhf, circuit boards and UHF tuner in the pics

[kx250rider]

If it's a 1958 model for sure, it has to be a 7, but it does look like a 9 to me (based on the cabinet style). That would make it closer to '59/'60.

I see it has printed circuit boards my CTC 7 does not could be a CTC 9 not sure when they started that.

[TV Engineer]

This set is either a CTC9 or 10.

You can tell the difference by what the vertical sweep tube(s) are/is...

If it uses a 6FQ7 and a 6AQ5, it's a 9.

If it uses a single 6EM7, it's a 10.

Confidential to damen...

If you have a CTC7 chassis that does not have printed circuit boards, I can assure you that it is the ONLY one EVER produced, and is truly one of a kind.

But I seriously doubt that...

RCA began using PC boards with their CTC4 chassis, and they never stopped.

6DQ5 and 6*** G (is faded) but has a Kinescope 21cyp22A CRT if that makes a difference,And not familiar at all with early RCA.

I'll go out on a limb here and say it's a late production "Mark Series" CTC-7. "The Meredith."
The CTC-9 sets did not use 5U4's.

Mine has circuit boards but they are plain with no print
