Be careful. I was excited about this inexpensive amp and told @Hornographic about it, and he pointed me to an online forum warning about potential fakes.
Not this model, but apparently someone ordered a tube amp from China, took it apart, and discovered that the output transformer was hollow. Inside was a small solid-state amp board and associated regulators. There was a filament supply to light the tubes up, but no high-voltage supply anywhere.
The audio path was wired in some way to use the tubes as path components. The tubes did nothing, other than when you removed a tube, the audio stopped for that channel.
I'm now curious to see if anyone has disassembled one of these enough to see the socket wiring, check for high voltage, etc.
Mind you, it was not this model (I don't think so, anyway), but if this is true it isn't cool.
Edit: One of the sites talking about it is here: http://audiokarma.org/forums/index.php?threads/nobsound-fake-hybrid-tube-amp.706645/
