Second song during rehearsal, it was getting quieter and quieter, until there was no sound. All of the power tubes appeared to be glowing, but as it was dying off, one or two of the power tubes was pretty bright orange. Threw it on standby, then turned it off. Tried it again an hour later, still nothing. The thing that confuses me is the power tubes still light up. Couldn't tell if the preamp tubes were glowing with the shields on them. Did I just smoke my power tubes? I recall reading something on TB about some faulty wiring or something in this amp, maybe that is the culprit? Bad fuse? Help this tube noob out!
