Title: HUM in power supply
Review: I've loved this Reciever, till about a month ago a low 60hz HUM appeared. It's constant on all inputs (when signal is availble on digitals) and is the same level regardless of volume. I eliminated the ground loop possibility. It's just under 2 yrs. old. I've replaced it with a Denon. I've yet to hear back from Onkyo on support, but will probably cost me shipping and take many weeks for repair. Anyone interested in a refubished unit about 2 months from now?I expected better.
Is the review positive or negative?
