Has anyone built one of the Trinity TripTop B-15 clone kits? They look to be well-engineered; DC-elevated heaters, switchable fixed/cathode bias, selectable output impedance, and enough guts to run 6L6s, 6550s or KT88s.
No, but I built the TC-15. My favorite amp ever: lives up to all of the claims and then some. And you won’t get better support than Coco, the owner. I would buy any of his kits that looked interesting to me, without reservation.
