A friend of mine recently hired me to do a few weeks hosting the open mic at the bar. I've been hauling out my PA, bass amp, guitar amps, and whatnot to make it happen. Last night the music was fair but all the entertainment came courtesy of the PA. It's Yorkville M1610- 1600W, 10 channel PA in a box. Mid set and middle of the night the thing poofs and voila- smoke plumes rise from the chassis being pulled in by the internal fans. An hour later it gave an encore performance and the photographer caught it this time. Surprisingly it ran the whole time without incident. After speaking to Yorkville's tech department I found out why it kept running. Somewhere along it's board the low xfrmr tap is crossing the high causing the capacitors (the smoking guns) to dry up and explode. Funny thing is when they blow they produce a nasty smoke and leak dielectic liquid all over. Nasty stuff for sure. IN other news, the photog also got a picture of the whole shebang. Everything in the second pic is what I take save the drum kit and the musicians. ;D The good news too is that the PA is repairable and should be up to stuff by next week's show. Now I've gotta spend some more time on the schematic and look for possible places the transformer's bridging from the HV to the LV line. Fun!!

Was it a "non-smoking establishment"?
