I was playing my guitar a little while ago and the power went from my and and the sound died straight away, could this be a valve gone??? how do i find out???
yeah but i'm not really sure how to find out without spending £20 on a new cable
If it doesn't power up at all, meaning you get nothing out of it, no lights on, etc. it's a fuse or the amp is now trash. If everything lights up but no sound, then it's loose connection or a tube.
If you cant power it up at all check the fuse/fuse's. If it powers up but power tubes are not glowing or the plate is glowing red its probably the tubes. Usually you dont loose total volume when a tube goes so im thinking its a fuse and your whole amp doesnt turn on.
