Try connecting an earth ground to the chassis like from a water pipe or baseboard heat element not the outlet ground pin (if it is a transformerless set use a cap to gnd).
If this lowers the noise good chance that it is some sort of local interference. Laptop and cell phone chargers are the worst offenders here at my place but there are many others.

When my pals were reading comic books
I was down in the basement in my dad's

Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.

Now I think I've got!
