i am looking for someone who can repair my tube amp. it's a fender blues deluxe reissue (made in usa). just a few minutes ago i played guitar and it was working fine. then after i had dinner, i went back to playing, and no sound was coming out. i have no idea what's wrong with it. i even tried plugging the guitar straight into the amp but just the same, no sound. if someone knows someone who's familiar with the workings of tube amps please give me their contact number. i would very much appreciate it. thanks a lot!
