No idea what happened. My Solo 50 just turned off, no lights and it won't turn back on. Fortunately my drummer's father is extremely good at that type of thing and is finding out whats wrong as we speak. I am scared that it is something bad/expensive. As soon as it cut off I swapped the power cable, changed the power tubes, and checked the fuse and neither of these made a difference. I really don't know what I could've done to it, its been running through a Furman, and I have a little fan behind it because the EL34s run a little bit hot, but that fan does its job perfectly.
I was able to finish band practice by using my ProCo RAT through a Yamaha keyboard amp....which sucked ass but got us through the rest of our songs. Really hoping its nothing major and something easily fixable that I can avoid in the future.
Sounds expensive or really bad.
