Today's Mystery Guest (RCA CTC-4)

Phil,
I couldn't find the original brochure, but I did find a scanned copy in my CTC-4 binder. The scans aren't too good, but can be read. At least the recommended dimensions are given for notching the flange, along with advise about supporting the bottom of the mask assembly, as the glass tube is much more heavy than the 21AX.

Yes, I had never lifted a metal tube before and I was startled at how much lighter it is than the glass counterpart.

I might be able to get that article through an inter-library loan (to make a better scan) if I can tell them the desired issue. As I read the first page, it is Sylvania News Technical Section, Summer-Fall 1965, volume 12, no. 2.
