Got your email but I don't have the diagrams handy here (its in storage). anyway, the CTC101 had the infamous flyback problem. The very high voltage was developed by multiple diodes between secondary windings, the CTC101 flyback had 3 diodes and 6 secondary sections. They should have used 6 diodes (and subsequently did on later models). The flyback would fail and that would take out the horiz out transistor. RCA used to sell a kit of these parts, and if I recall correctly, a set of focus pots too. But that was 20 years ago. Many CTC101s had warranty work for this, maybe your set has the replacement flyback already in it? If the set's not dead, it may have a replacement.
Be aware that portions of the CTC101 chassis are "hot" (direct connection to the line) and other portions are isolated from the line. Tuner and video and vertical circuits IIRC are isolated, but the horiz circuits are hot. Parts of the yoke are hot, and others isolated.
I used to work at RCA Labs at the time...
