Ive had a couple Tremonti PRS guitars and they were decent. But not a fan of PRS amps.
It would be like Marshall amps UK making a Les Paul.
I suspect your amp crapped out because it wasn't built well.
Building Indonesian guitars is one thing but building good Thermionic valve amplifiers comes from a completely different solar system.
Having said all that i feel bad for you cuz amp problems suck.
