I just went down the Automatic Gain Control rabbit hole, I love learning about this stuff but much of it is over my head. Also I'm not sure I would be able to tell if the image is too grainy, most things are pretty grainy over RF.

If you have some direction as to where I should look let me know. There are lots of pots and I'm a little nervous to just start poking around.
Your picture shows what looks like an Orange Drop replacement for the 22-5001 white safety capacitor. This is good news, but it's not the big run capacitor I'm talking about. This picture shows the capacitor that FAILED in my 1976 Zenith CCII 17" set similar to yours, 17GC4x chassis. It may fail, it may not, but I've had four of them go bad just in the past two years.
