There was a schematic/how-to on building an external filter for the power leads to a radio to eliminate alternator whine? I can remember it, but can't seem to find it...all I remember is it was a box, a magnet, and capacitor?
Anyone have that handy? I need to build one for the truck...my PC76XL must have better power supply filtering than this General HP40W.
