Ctc ??
 

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!

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

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

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.

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.

Mine has circuit boards but they are plain with no print

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.

I cleaned the stamping up it looks like it could be a 7 but it has side mounted chasis I hear that was only on the 9 and above, I cant find much info on the 5-7 or 9 differences, Steve very nice ct-100 BTW!

I may be incorrect, but I believe the CTC-7 chassis has a vertical (side mounted chassis). If there is a tube chart on the inside of the cabinet the CTC-7 has a pair of 12BH7 tubes for R-Y B-Y color amps and the G-Y color amp.
The CTC-9 has a pair of 6CG7 tubes for the B-Y R-Y color amps and the G-Y color amp. This should tell you what chassis you have.

As you can see that chart is very hard to read but it is there, maybe this will help with a better chasis pic too

Dug out my SAMS CTC-7 Photofact.
Comparing your tube chart photo, not easy on the eyes, to my SAMS CTC-7 tube layout shows that they are not the same. There should be NO 12BH7A tubes on your tube chart. I now believe your set is the CTC-9 "Boswell" model.
The SAMS also confirms that the CTC-7 has a vertical (side mounted) chassis.

The CTC-7 black metal "Meredith" and CTC-9 "Boswell" are pretty much identical in appearence.

Thanks for the nice comment on my CT-100.

You're correct; all 7s through 11s are side mount chassis. The 7s I've seen, all had side controls and side aux control door, whereas the 9 had side or front controls, and front aux controls (exposed at bottom).
