ok, so i have a JCM800 and was changing the tubes to yellow jackets (EL84) because the amp is too loud...when i was carrying my amp to connect it to my cab, i turned the on button without noticing it and when i went to connect it to the wall plug, it made and loud noise because it was already on and now it doesn't work...what's wrong with it?? did i burned the tubes? the fuses?
