Wavebourn non ordinary Push Pull tube amplifier

“Ordinary Push Pull? Nope! Late development pentodes with local feedback, planar triodes and pentodes designed first for military then for TV, solid state assisted power supplies and voltage stabilizers. Amps with such parameters would occupy huge chests and look gorgeous. Everything that we were taught to design for military conditions, but with nice fine high end audio in mind..
