Femanist!!!!!!!! Walter.

Possibly. lack of earth, or, earth loop, i.e., too many earths!

Worth a try. does your amp have an earth point, if so disconnect it and see if ok.
Not sure about Canadian wiring, is it the same as US. On two pin plugs, I even found that reversing one,(UK)!! did the trick.
Difficult to be precise from a distance.
Did the hum vary with volume? Walter.

It is an earth loop, try taking one earth away at a time, but be sure to leave one for safety. Trial and error I'm afraid, wish I was nearer!!! Try another lead to your TV, just in case. Walter.
