Make sure your hot and neutral wires aren't reversed.
I was going to suggest running an extension cord from another outlet to see if there may be polarity or grounding issues in that particular one.
Sounds ridiculous, doesn't it? But it happens more than any of you would believe. I used to work with a "C" electrician (we had an "ABC" progression for folks with electrical backgrounds that didn't want to go thru an apprenticeship) who had been a house wirer in Pakistan, before he emigrated to the States. He could not get it thru his head just how dangerous it was to use the neutral wire on a switch and to mix up the wires on an outlet and I had to check every connection he made, which enraged him.
Believe me, it happens. I won't go into details about the dangers. Too many to list. All you have to do to ensure your receptacles are properly polarized is buy a device at a Home Depot or an electrical supplier that will check the polarity of a receptacle. Here's a link to typical device. They come in many different configurations, but all check for proper polarity.
A voltage tester can also be used. When you look at a 120VAC outlet the two holes that are side by side are for the hot and neutral wires. The plug below them, by itself, is the ground plug. The two holes that are side by side are different sizes. The smaller of the holes should be connected to the hot wire. Using a voltage tester, just put one probe in the smaller hole and the other probe in the ground hole. You should read over 110VAC on the meter. If you don't, don't use the outlet. Get it fixed.
I've seen licensed electricians wire up outlets improperly. Best to check polarity after any electrical installation.
I think armophob was suggesting to power the amp via a long extension cord, so to connect it to another outlet and/or circuit, to see if the current one was causing the problem.
Yup, read another post wrong....:nono2:
Hey everyone ... thanks much for all the suggestions and assistance ... I have exhausted everything on my end - this Marantz receiver is getting a RA -
I had a similar problem with my car stereo and my amp. It was just last week that I solved it. Some radio stations (out of Detroit) would not come in at all and had a weird static noise when I tuned to them however in my moms SUV and my dads truck the stations came in just fine. They stopped coming in when I installed a Kenwood navigation system which was also the same time I installed the amp for the subwoofers.
That was in January and I just got a new Sony navigation system and I tested the stations before I connected the amp and they worked then I connected the amp and they didn't
Turns out, there was a problem with the way that the amp was grounded, I fixed it and now everything works as it should. You were lucky to find the problem out so soon, I thought I tried everything and then I just accepted it then someone asked if it was how the amp was grounded, turned out that was the problem.
