What's the frequency Kenneth?

Hi,

I need some help, if possible. After moving and months of looking for a place to live and waiting for a stand to set my gear up, I finally got my system put back together. Thor electronics, Accuphase CD player and Tannoy speakers. Boy did it sound sweet! While I was checking the bias on my amps, with no music playing, I heard something faint and low coming from the speakers. After putting my ear close, I could tell it was a radio station. WHAT???!!! So low, it was almost undiscernable, but still there. Not obvious at all during music playing, but still there. Now, if I wasn't an obsessive, compulsive neurotic ( Wait - What was that noise?) about my gear, this would not bother me. But it does. I'd like to fix it, if possible, but have no idea where to start. Any suggestions? Thanks for your help.

Well, if you're not using shielded interconnects, maybe you should try that, or go to RadioShack and get some RFI filters to install on the interconnects and power cords. Anyway, that's where I'd start. The longer the cable run, the more likely it could be acting as an antenna.

The tube gear may be more prone to picking up RFI than your solid-state components.

Dave,

The thread title brought a smile to my face remembering how Dan Rather was pummeled while being asked, "Kenneth, what is the frequency?" Thanks for the memories.

You might try shielded interconnects as suggested and check ground/power. Most likely it is a lack of shielding for RFI on the ICs (at least that is what I had seen before)...

My brother had the same experience, only worse. He traced it his satelite TV decoder. His solution was to plug the satelite decoder into a Monster power strip instead of the basic strip he was using.
