RE: Isolate the TV AC power from the other stuff, so IMO yes a Triplite might work.

Yup, they get noisy. There was a bulletin about it but they of course did not offer any refund or partial.

Turning the picture controls down doesn't help because you got those +200 and -200 volts switching all the time, and the pixel is switched on by about a 50 volt grid, or exciter. (do not take these voltage levels to the bank, and in fact they are specified for each unit separately due to differences in each tube manufactured)The pixwl is then turned off at a specifies time by the sustain boards.

All the voltage is still there even if the picture is all black.

Now if getting amplified through the stereo is a new phenomenon I would suspect grounds or filter caps. If you haven't had it hooked up to an amp before and now are just noticing this, it might just be a bad design.

This sounds like one of those tough dogs to fix. To get the hum out of the output audio can be a real PITA. As a Man who can wire a whole house ad has had high end electricians in the family I am not telling you to do this, but cutting the ground pin off the AC cord might help. Don't vut it right away just try one of those adapter thing we all have had to use, and do not connect the ground. This is a test, this eliminates ground current as the fault. If floating the ground works, that means to address the wiring in your house.

Other than that, the very most likely fault is bad grounds or filters in the TV. Actually, if are lucky you might only have to tighten some screws on the circuit boars in the TV, but that is extremely rare. Te thing would have to have been subjected to stress/vibration for that.
