Might be time for new sockets. IIRC surplus sales of Nebraska had the correct sockets for these last time I checked (a good 3 years ago). I've been wanting to buy three new Video IF sockets for my CTC-4, but have yet to come up with a minimum order to merit purchasing them, and like you I've got alignment issues and lack the knowledge/equipment/time to do pick up the craft......After I graduate this year I hope to have sufficient free time and monies to gear up for TV alignment.

To give direct video input another shot, I disconnected the output from the video detector to the 1st video amp, and injected a video signal to the video amp grid. I started with a B/W crosshatch pattern so that I could adjust the screen background, etc., to make a normal display.
 Then I switched to a color bar pattern.  Adjusting the Color control, etc., gives nothing like a normal color-bar progression, so I'll check out the color circuits. Phil Nelson
