For the jail bars, I think it's clear that you're not going to fix it by shot gunning parts. It's going to take a good oscilloscope and someone who knows how to use it. That old scope you have won't cut it for finding a subtle problem like this. I would start at the CRT socket to see if the jail bars are on the cathodes, G1, or G2 (careful that you don't exceed the voltage limit of the scope and probe with the G2, a HV probe might be needed).

If there's nothing on the CRT socket, then you probably have a horizontal deflection issue (a slight change in the scanning speed as the beam goes across the screen will cause a change in brightness).

I wish there were a place in Los Angeles that rented scopes. I did find one place, but the cost of renting for a week was close to buying a used one (of course buying used is risky as most lower cost units are "untested").
