I've seen Chinese tube amps go up in smoke as well.
But the fact is that tube amps aren't cheap to make correctly and the US labor costs are horribly high. There are American options that are worthy in the $1500 range but you'll probably have to settle for used components, such as the Manley Stingray, Conrad Johnson CAV-50, VAC Williamson, VTL-IT 85, Cary SLI-80. I can't think of any new ones, other than the Cronus, in this price range. Just a fact of life I guess!
