I was playing my Peavey Valveking the other day while jamming with my drummer. I had it around 5 or 6, and right in the middle of playing it cut off. I tried cutting it off and letting it cool down, but it will not cut back on. The light won't come on or anything.

I'm primarily an acoustic player, but I've started jamming a lot with different bands lately. I have no idea about anything with amps haha. So any help would be great.
