Well, I was just having a little Schroeder 1210 vs. EA Wizzy (just got it yesterday) shootout in my living room, and my faithful ol' PLX-3002 just totally crapped out. I was playing at a moderate volume (everything pretty much @ 12 o'clock) and had just adjusted the gain on my Glock pre very slightly, and then the power amp just suddenly went very quiet and fuzzy, with the clip light ping-ponging back and forth between the channels. (Just the red light was lighting -- none of the green lights.) I experimented with parallel vs. single input, and no change. Still just quiet, fuzzy notes, with intermittent dropouts as it ping-ponged around. Turned it off for awhile, but no change when I tried again. Confirmed that it is indeed the power amp, as another pre did the same thing through it, and the "sound" it's now making comes out the same from both cabs. When it powers off, there is a VERY loud thump. I had it much louder at my gig last night, of course (but nothing different than I've been doing for all the years I've had it). The Glock pre is new in the last couple months, but I can't believe that would kill it. When I first got the Glock I experimented a lot with the gain/volume, with no problems. Got another gig tonight, so it looks like I need to piece a back-up rig together. Any suggestions? Time to send it in for service?
