In Reply to: Try shorting plugs on the preamp inputs. posted by Al Sekela on October 28, 2010 at 14:56:55:
Well, I only had one pair of shorting plugs and I only could find one.
So I unplugged the source selected and plugged one shorting plug in and the AM station went away. So I did some more 'playing' around. Turns out that the radio station come and leaves sometimes when I touch the RCA input jack, also after leaving the AM station came back when I switched sources.
Looks to me that the AM station comes in with a ground loop problem, though I don't hear a ground loop problem.
