Power Wedge 116
I have an old Power Wedge 116 Line conditioner and it has a slight "hum". I replaced the fuses, but that doesn't seem to help. At this point I can't afford to update this part of my home theater system; does anyone have any suggestions for reducing / eliminating the "hum"?
Home theater components: Anthem MRX-1120 receiver [plugged directly into the wall outlet]; the following are plugged into the Power Wedge 116 line conditioner: Oppo BDP-105D Blu Ray disc player, Net Gear ProSafe Gygabit switch [model: GS105], and an Actiontec ECB6200 bonded MoCA 2.0 network adapter. I have unplugged each component from the Power Wedge 116 and still get a "hum". Obviously, when I unplug the Power Wedge 116 from the wall outlet, there is no "hum". I would appreciate any suggestions you could offer.
