A line conditioner would most likely solve the problem. But 60Hz noise should never enter the amplifier circuits. It's a result of poor filtering and/or lay-out and/or too few layers on the printed circuit boards. Any recommendations here? I have seen that APC sells one but it looked to be $300. But this had more than I need. Do they sell just line filters that can be plugged in or are they hard-wired?
