Hey guys, I've got a little dilemma here, my Vox AC4TV8 suddenly stopped working. I was just playing at practice when suddenly it went silent. No sound, LED still ON, just a little faint hum. I turned it off for 30 minutes and turned it on again, there was a LITTLE sound at first then 3-5 seconds later it went out again like turning down the volume but really fast. tried it again a couple of hours later, no more sound not even a little except for that really FAINT hum and the led indicator still ON. I changed the tube, same problem. The fuse doesn't seem to be blown, if they're blown the led indicator wouldn't go ON right?(if I'm getting this right) I'm in Japan and the closest Amp tech is like 400 Kilometers away so I'd rather try and fix this myself if I can. Thanks in advanced!
