Wow, great find! Thanks for sharing!
But this video relates to hand built tubes, and there are also factories producing tubes in assembly lines in large quantities...
WHAT, tubes that are NOT hand built... what BLASPHAMEY IS THIS! lol
I'm sure there is, either way I like these tubes over my Solid States ^^ even my $100 tube amp out performs my $100 solid states. I do how ever need to compare an O2 to my little tube... b4 I shun the use of Stationary Solid States for ever xD
but... MAN this tube hybrid sounds NICE :D, I can only imagine how a pure Tube amp will sound *drooooools*
