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.

@foghorn1 I recently picked up a 1118 on the cheap, but haven't really used it yet.  It makes a quiet physical hum, though.  Seemed to slightly reduce a little noise from a tube amp.  What's your impression of the 116?

@stringreen just curious why you recommend not using these things....

Some people have used Humbusters for that kind of problem, but they will only work if the hum is a result of "dirty" AC power.  Folks report variable results.

The PS Audio Humbuster removes dc offset from the ac mains which can cause transformer hum which is not the same as dirty power
