Outputting 32 watts per channel on 6L6GC tubes or 40 watts on KT88, the Super40 weighs 34 pounds and runs on the low-feedback, push-pull topology.

    So nice! Back to Basics. Since Nagra has lost its Marbles on Pricing, €29000 for The VPA monos! Moi never left Tubes so I got hold of Audio Power Labs Oil Cooled Class A Jewels that mark the Epitome of my Audio Life. Your Amps compete with McGeary Amps in Virginia !
