Re: My Fender Bassman is come!!!
Whatever you do, do not open up the amp and start poking around. Tube amps, even when turned off, can have enough charge in the capacitors to potentially kill you. If it was working when he shipped it, and nothing obvious is wrong with it, then it should hopefully be an easy fix. I'd recommend taking it to an amp tech, having him fix it, then submit an insurance claim to UPS to cover the repair bill. If you're only asking for the cost of the repair and not the cost of the amp, there's a good chance UPS will pay up.
