I just bought a brand new head and played it the other day and it was my amp to replace all amps. Last night I went to play and it will not power up at all, zero zilch, nothing. I had it plugged into a surge protector with my other amps and it was not tripped and the other amps are working fine. I tried a different power cord and still nothing. The fuse looks fine but Im thinking that's the only thing it could be. Anyone have any suggestions?
