Newby problem with hum

First thing to do is go to psaudio.com as they have a section on hum on there web page as it's very helpful, and it will walk you through step by step until you have isolated the problem. The chockes are no good for sound. I think it's your LP! but check out there web site as it will give you great info. Happy fixen!

Smccull, you could have a cable tv ground loop problem. This can be solved by getting a pair of matching transformers($5) and put them in series with the cable tv line. Check your cable tv ground and the ground wire across your water meter. Cheater plugs will work also. Try putting in a dedicated 20amp 12 wire line in and put the cheater plug at the outlet. I am not to crazy about putting cheaters after the filter. Get an A.W. Sperry outlet tester (Home Depot $6)and test the outlet and all outlets in your house for polarity. Put your cheater plug in your dedicated outlet and test the outlet again. It should still light up correct, even though the ground is out. Why, because the ground and nuetral wire are on the same bus in the main box. If you are still getting a ground hum, call an electrician an put in an isolated ground in.

I had a ground loop/hum problem that was evident in my audio set up. Mine turned out to be the TV cable line. A simple test would be to disconnet your cable TV from the source or wall connecton and see if the problem goes away. I put a filter on the cable line and my hum has gone away.

Actually there is a preamp in this system. It is in the same case as the power amp. I wonder if the integrated amp could be modified/upgraded, or at least checked to see if it is grounded properly or well enough??

Can you upgrade the power cords on these units?
