got it back from the tech, he had to decline working on it because there's a blown transformer and apparantly mesa doesn't sell their transformers to independents and he wasn't down with throwing anything in there. so 260 last week for tubes and probably another 2-300 for repairs. this thing sounds great, but right now i just want to put dynamite in it and blow it up. P.S. I heard blown transformers come from playing your amp without it being plugged into a cab, which is something I do not do so I was wondering if there's anything else that could cause this or if my house is haunted.
