Made Out Like A Fat Rat

Last week when I purchased my Speakerlab Khorns the seller gave me a Luxman R-117 receiver and an old Denon cd player. I got a killer deal on the Khorns as it was. The seller told me that the R-117 had a channel going out and if I didn't take it he was going to throw it out. Well, tonight I finally plugged it in and checked it out. The left channel was scratchy and cutting out intermittently. So, I got out the old Deoxit and hit all the pots and worked them back and forth for a while and like a miracle the darn thing plays beautifully now. It does have one issue though. When there is power to it you can here a buzzing noise through the speakers even when there is no source selected and with speaker volume all the way down. I am wondering if this could be an easy fix or if this is a symptom of something serious. When there is music playing you can't here the buzz. It does not get louder with the volume. Any ideas? Also, when I had my Sansui plugged in, as soon as I plugged in the Luxman to the outlet I heard a little pop noise over the speakers hooked to the Sansui. I thought that was pretty strange.

sounds like a symptom of needing power supply work

Tom...I had this exact sounding problem with a Nakamichi receiver I bought off of the bay...cleaned it with DeOxit (after trying and failing using the "bargain" brands) and it has been working perfectly for over two years now...

leave it on for 24 hrs and check the buzz issue again....if it improves...there's a bad cap somewhere....since it is unlikely the unit has dual power supplies, it's not likely to be a power supply issue since you said it's only in one channel.....if it has split power supplies....then power supplies could be suspect....could also be a bad ground on one side of the unit.
