So I'm practicing with my band, and all of a sudden, my beloved portaflex, which I've never had problems with, starts cutting out, and the fault light comes on. So we stop playing, and I check to see if it's over heated. It doesn't seem to be, but we take a break and let it rest anyways. Come back to start playing again, hit the on switch...nothing. The power switch glows red when I switch it on, but the purple led stays off, and it doesn't make noise when I play. I've tried different power outlets, different cables, everything I could think of. Any suggestions before I talk to ampeg?
