Photo 1 is a good TV picture.
Photo 2 shows the horizontal brightening.
Seems to be linked to the white text displayed.
AGC issue? what do the experts think?
Does audio buzz when text is displayed?
Photo 3, EHT & H Scan cage section.
Red anode connector wire seems to have a cut or brittle plastic breakup.
See zone highlighted by red circle.

Audio does not seem to be buzzing to any extent that I am able to notice even when audio is turned up a ton. No issue in that area, audio is pretty clear despite no work being done with tuning. I may attempt to fiddle with the AGC controls on the back more and see how this affects it. I was using VHF channel 4 and another time 6. Using one of those RF modulators that lets you choose a channel. Very handy for looking at UHF tuner I might add. Will take a look at red wire and follow up. Wouldn't be surprised though as the red anode wire is still original. I have some spare HV voltage anode wire I can replace with if needed luckily.
