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).

The tube layout posted above shows 6EA8s for 1st sound and Color killer. Those tubes would be correct for a CTC9.... a CTC7 uses 6U8s for those two functions.
