Tube Amp in Taiwan

[mresseguie]

This may be a prototype or a pre-production model made by someone (don't know who yet) in Taiwan. There's next to no information on it, but I thought I'd snap a photo and show you. Anyone recognise the big tubes?

I got a partial answer on which tubes were used from the guy who built this amp. He suppied this information:  ux250,px350

I'd never heard of either tube nor have I seen them used in audio gear, but I'm still pretty much a tube noob.

The guy's English seems to be pretty limited (and our conversation was in English), but he did invite me over for a listen someday.
