Cable tv induced power hum

I had the same problem once. I fixed a littel cheaper than the other guys. I converted the 75 ohm signal to 300 ohm then back to 75 ohm and the problem went away. You can get such devices at Radio Shack.

I agree with Flyguy and Jaguar. The Mondial MAGIC works, and is the "correct" way of solving a ground loop problem. And, no, I don't work for Mondial - just a fan of intelligent engineering.

I forgot - for info on MAGIC, here is the URL: http://www.mondialdesigns.com/acurus/acuhomef.htm Good luck!

Agreed, 100% with the "Magic" box...it works as advertised! Mike Classe'SSP-25, JoLida 502A,Pioneer Elite DV-05, Denon analog table w/ Grado signature cartrige, Theil 2 2 mains, Paradigm center, B$W surrounds, NAD amps for center and surrounds.

Hi--Thanks for all your great advice. To followup: 1. I ordered and installed the Madrigal M.A.G.I.C. and it eliminted the power hum. 2. I had the cable company come out and check my groud. Seems as though when the @home cable guys installed my internet cable they didn't re-ground or else changed a ground or a lead or something. The regualar cable guy did something (at least he told my wife he did) to eliminate the hum. 3. Now I am left with a speaker hiss in the system. Just enough to be noticeable at low levels. I'm investigatin power conditioner and balancers and I'm really confused: Bybee Power Conditioners and Quantum line filter; CinePro Power 20, Tice Power Block III, Richard Gray The Power Company, PS Audio. I have a Monster MTS 2000, but it's not doing the full job. What way to go? Any ideas or your experience would be appreciated. Thanks
