At about 12:30 this morning, one of my two subwoofers awoke itself with a loud & continuing 60 Hz. hum. The other (connected to the same circuit) remained asleep. Only when I shut off the plate amplifier switch did the buzz stop. The preamp was in standby mode. This morning, when I turned the sub on, the hum returns.
Bad capacitor?

Boomzilla Caps were my first thought, assuming you removed the input cables already. Tony |

Boomzilla Caps were my first thought, assuming you removed the input cables already. Tony With mine, it was a bad feed splitter. Removed the splitter ( cable ) and my midnight caller was gone. Try replacing the feed cable to that sub, worked for me. Remember this thread? emotivalounge.proboards.com/thread/43052/subs-keep-waking-sleep-help |

Cable IS the culprit. When I unplug, the thing's dead silent. Why would a cable fail at 12:30 am? No movement, no signal, no reason...

Boom, you need to head down to Rampart Street and leave an offering at the Voodoo Spiritual Temple. I recommend a bottle of good Puerto Rican rum.
