That's a great tip, Larry. Would you mind detailing how these ferrite rings
are installed?

With the controls of the system set for normal listening, stop the CD,
tape or whatever. Turn up the volume control about 5 or 10 db and
listen carefully. If you don't hear any stray signals, as they say,
"Don't fix it if it ain't broke." If you do hear a bit of a local
brodcast station or ???, try the ferrite beads.
