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.
