Ok... I started messing with this thing last night and found that for some reason, on my main Empeg player, the Dimmer is causing this static when listening to AM if the Empeg is on. With the Empeg off, no static. With the Empeg on but the Dimmer turned down below 50%, no static. This player is not hooked directly to anything except my Alpine headunit. Not to my antenna, not the amps, not headlights, nothing... So what's going on? Anyone who understands the internal wiring of the Empeg that can enlighten me on this. It's only this particular player that does it, none of my others have this problem.
