Ctc ??

[damen]

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.

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

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).
