Hey rockers i was playin a gig last night and i went to hook up my amp this morning and it played for about 5 minutes and then just shut of on me the lights dont come on even though the tubes do when it is turned on and the footswitch doesnt work eaither, i think and im hoping that its the pre-amp tube that gave out but i wanted to knwo if anyone ever had the same situation an if i could get some tips, this is the first time im having this happen.
