So this TV has been playing well, I replaced the HV lead, cleaned the cage, replaced the tubes in the tuner. I also cleaned the "noise gate" pot, it was scratchy and made the picture go wavy/buzzy intermittently.
only quirk I have now is some buzz in the audio which can sometimes be minimized with adjustment of the fine tuning. Perhaps I have a dirty tuner? or could it be alignment related?
