This one is a superior class AB push-pull configuration tube amplifier project delivering 80 Watt RMS per channel. Four 6550 high power tetrode vacuum tubes in triode mode and class AB2 push-pull ...

The amplifier project utilizes vacuum tubes on the preamplifier section to produce a push pull output stage while using point-to-point connections. Each of the tubes are consuming 940 mA of current ...

The GA-10 is an audiophile-grade headphone amplifier that features the SEPP (single-ended push-pull) circuit with eight vacuum tubes, a linear transformer, and direct tube output. The vacuum tubes ...

Double-ended topologies, such as push-pull, half-bridge and full-bridge, allow higher efficiencies and greater power densities compared with common single-ended topologies, such as flyback and forward ...
