Hi all, wondering if anyone could help me out here. Ive had a peavey valveking 112 for a couple of months now and its been fine, but for some reason lately the sound keeps dying. You know when you flick the standby switch and the sound slowly fades out before you turn off the power switch? Thats what mine keeps doing despite me not flicking the standby switch. I've tried getting a new mains cable for it (the three pointed one) and still no improvement-any ideas what might be wrong?

cheers in advance
it might be the input jacks. well at least you should hope, cause on my 212 that happened and i took it in thinking it was the input jacks and turns out it has an internal electircal problem.
