Maybe you could have swapped the chassis of the ash tray set into the older set cabinet. To be reunited with the CRT from the ash tray set. That would take care of the vertical height issue. The tuners might be an issue, but they all have a standard IF frequency. Only issue might be supply voltages, but you probably can create workarounds for that. But it sounds like you made the ashtray CRT work with teh CTC108 chassis.

I figured the retrace cap must have been open (like those GEs did), but the cap was good. Stunned to find a bad flyback.
According to our field rep, it had something to do with a bad batch of epoxy used to encapsulate the transformer.

I worked for RCA Sarnoff Labs back then. The flyback transformers used six windings, and 3 diodes to create the very high voltage for the CRT. They thought they could get away with just the 3 diodes, cheaper. Wrong! The terminations of the windings and diodes were a stake style, which created electrostatic stress points. Had they used 6 diodes, one diode per winding (winding-diode-winding-diode-winding-diode-winding-diode-winding-diode-winding-diode) these stresses would have been half as intense, and the flyback transformer would not have failed. When they made the 6 diode flyback, they used a different color epoxy than what they used in the 3 diode flybacks.
I had a CTC101 and loved the picture it made. It had the line comb filter, for better chroma-luma separation (something I did a lot of work and patents on at the RCA Labs). Unfortunately, that CTC101 did have the bad flyback, but it lasted about 10 years before shorting out...
