It is stereo SE amplifie using 300B tube as power tube. Driver tube is 300B. Pure class A1, Zero NFB. Price in case you see this amp is sold out 3800USD plus shipping fee, tubes are not included

This is new design of 300B tube amplifier, using O.U.D.D.C schematic (Detail here > http://soundgate.net/product/MTQ1MA...highend is bringing the best sound ever for the amp.

In prototype version, I use all Luxman transformers. But in order version the transformer will be difference.

Using driver tube 300B for driving 300B make the color of sound more 300B characteristic. This is the first time I do stereo version of 300B drive 300B.
