[QUOTE="jlaubza, post: 973308, member: 21934"] Humming problem has been solved - turns out not the power supply but a low level hum through the speaker itself. The cause? A faulty commercially made (TEAC label) coax cable. I was straightening out wiring behind my amp, moved this cable and heard a crackling, scratchy type sound coming out of the subwoofer. I replaced this cable and the hum was gone. I tested the cable with a multimeter for shorts but it tested clean, no matter how much I twisted and tugged it. Anyway, it has been sent to the recycle bin. [/QUOTE]
