I made some valve+BTJ class "A" amplifier with 2N3055. But my amplifier use other type of output stage, samething like Nelson Pass class "A" design.
I used BC546+BD139+4x2N20355, as output follower, and same as current regulator. E88CC as driver. It sound nice with some feedback applied.


Your heatsinks looks sexy
