Tech question - picture distortion

[zenith2134]

I've encountered one ctc-120 since I started messing with TVs a few years back.

FindmKeepm certainly knows for sure though, and judging by the repair tips he posted, your problem could just be a weak or shorted transistor in the video circuit or a cap.

But by your description the first things I would check on a set of this age are the focus, and the rf/if section but be careful in the latter sections...
