I have an Ampeg SVT 210-HE that sat in my back room for 3-4 weeks while I favored my 1x15 cab. It had always performed perfectly. I took to soundcheck for a gig last Saturday, got everything plugged in, and. . . nothing. No sound at all. After recovering from a near heart attack thinking that my WT800 head was on the fritz, I started switching cables, output jacks, input jacks, everything I could think of that might have been the problem. Eventually, I plugged into a PA cab briefly and everything was fine. I went back to my trusty 1x15 cab and the gig went on. Last night, I unscrewed the input jack/wiring plate from the back of the 2x10 cab and shined the ol' maglight in there, hoping to see something obvious and prepared to be disappointed. There, on the bottom of the cab, was laying the speaker wire that connected one speaker to the other. Somehow it had just come off the connector. I reached in, slid it back on, and she was good as new. I can't imagine how one of those connectors falls off. To make it even more unlikely, the connector in question was on top of the speaker, so the law of gravity was circumvented when the connector wriggled upwards off the connector so it could fall off. Anybody else ever have this happen?
