[QUOTE=old_tv_nut;3222568]I have an ad for the exact model of CTC-5 I have. It features Mrs. Robert Calvert of 222 Nelson Road, Scarsdale, NY, touting how beautiful and easy to tune the pictures are, and that they have not needed a service call in a year.

Wayne,

I have a CTC-5 Deluxe chassis model. It has a 21FBP22A/21GUP22 replacement tube. Fortunately it has an RCA metal to glass tube mounting conversion kit. This allows the installation of the new tube to the existing mounting receptacles w/o using the 21AX plastic shield. The original yoke was retained.These kits are extremely rare and I have never seen another. Sorry I didn't post these photos earlier.

That looks like the stock CRT back plate and mount ears out of a CTC9.... makes me wonder if the mounting holes on the 5 and 9 masks are the same and the mount kit was simply RCA grabbing parts off the 9 line.
I have a 5 and a 9 maybe I should do an experiment to confirm.

Tom,

I'd be very curious to see the results of your comparison. The CTC-9 mounting plate does look similar. Difficult to see in the SAMS photo.
