Vertical Line - Raytheon Porthole 1602
Installed a NOS 16AP4 CRT in my Raytheon Porthole 1602 Chassis 16AX23.
It tested strong with my CRT tester and has better contrast than my old 16AP4. Been several years since I was active in restoring antique TVs. The Video source is a Blonder Tongue modulator and a DVD player. TV and modulator antenna not but about 20 feet apart. Anyway, note the vertical line in the middle of the picture. I do get some intermittant crackling in the Speaker even with the Audio turned all the way down. I did not tune the TV after I had recapped it. Got any ideas on how I can improve the picture quality?
