Did a gig last night, I walked in and took one look at the wall outlets, and the electrician in me said, go get the Fluke Multi-meter, so I said don't plug anything in till I check voltages, well people don't listen and everyone was in a hurry and my gear was plugged in and turned on, by the nitwhit bandleader, who promptly said I have poopie gear ( Tome Hammer 500 ), cause it turned on only briefly, turns out one set of outlets was 242 volts, and I'm fearing that cooked my amp, club owner is totally ambivalent to the issue, pretty much says it isn't so, bandmate says it's not his problem, even after I told every one not to plug in, till things check out
