Solution to a ground loop problem

answer: Jensen Transformer part #VRD-1FF. Got one new of ebay for 50 dollars..worked like a champ. I hvae cut/pasted form a previous post...

Check the A/c plug on the back of our amp...if there's a 3rd prong on the unit, that is more than likely the cause of your problem. The extra conector will generate a 60 hz cyle humm which may be coming through you cable TV...try disconnecting your cable vision and see if the problem does away. I had the same problem and the culprit was my cable which was not properly grounded. Unfortunately, the only workaround was to buy a cheater plug (which as I understand can be a fire hazard), OR purchase a Jenson transformer ground loop isolater. I picked one up off Ebay a few months ago for 50 dollars and the problem was solved immediately. Here is the part # VRD-1FF and here is the website to lern more about the product www.jensen-transformers.com/

Better yet: Get the cable company to reposition and reconnect their ground. Then you won't need a band-aid to block the loop.

I had this same problem. Here are the two parts you need, total cost $11:

Connect the cable coax wire to the transformer/splitter.
Connect the wires from the transformer/splitter to the 75-ohm coax combiner/splitter.
Connect the 75-ohm coax combiner/spltter to the input on your TV.
This was done for me by the cable TV guy. Worked like a charm. Why? I don't know. I guess it breaks the ground loop.

The best solution of all is the Mondial Magic Brick. You can get it through Music Direct in Chicago. I had the same problem--the Magic Brick works like a charm.

I had the same problem at one time. I disconnected everything and then carefully reconnected - hum went away. Try it - hope this works for you like it did for me.
