Would a power conditioner stop a 60 cycle hum ?

........had an electrician stop by to see if i can get rid of a 60 cycle/ 120 cycle hum .......all outlets would need to be run off one leg into the box and grounded with a dedicated outlet to stop the noie that I have. The problem is .....the walls and celiing would need to be cut in order to connect the runs and be able to run the one line to the circuit box......that's not going to happen and that will cost a buck or two ....so would good power conditioner with all my power cords plugged into it- and then that one line that does go to the circuit box posibly clear this issue up ....need had a ground lop hum ....what a pain in the rear !!!! Thank you in advance

Garebear,

I assume all your audio equipment is plugged into one duplex receptacle or maybe 2 duplex receptacles but both are fed from the same branch circuit breaker. Correct?

Do you have a CATV box receiver connected to the audio system? If yes that is more than likely the problem. A difference of potential, voltage, exists between the CATV Cable Company’s coax shield and the safety equipment ground of the 120V AC power system feeding your audio equipment.

If you do have a CATV receiver hooked up to your audio system try disconnecting the Cable Company's Coax cable from the receiver and see if that stops the ground loop hum.

If it does buy one of these. A Cable TV isolator.

...thanks everyone but what the hell is a Hum X from Ebtech. The system is on a seperate circuit that my cable TV, I worked with an electrician who moved the ground wire of the cable to a difeerent part of the circuit box......did not work.

I worked with an electrician who moved the ground wire of the cable to a difeerent part of the circuit box......did not work.

What exactly did he do? Did he go outside the house, locate the CATV Company's coax cable grounding block and rework where the block is bonded, connected, to the main grounding system of the electrical service of your home?

IF,..... the audio system is connected to the CATV system and the CATV company's feed coax cable shield Grounding Block is not properly bonded, connected, to the grounding electrode system of your home's electrical service a difference of potential will exist between the coax shield and the equipment ground used at the electrical receptacles your audio equipment is plugged into. That difference of potential will cause a ground loop hum.

SIMPLE TEST......
Disconnect the Cable Company's coax cable from their Cable box receiver. It will take you about 30 seconds to disconnect the coax cable. Check for hum......
