Audio Power Amplifiers using Current Dumping

[tomhajjar]

Here are four variations of the same audio power amplifier topology using Quad Audio's famous Current Dumping technique. The amplifiers were presented on the diyAudio forum and simulated in LTspice. The TL071 sub-circuit accurately models VCC/VEE currents.

The four variants use output stages based of BJT, Darlington, Mosfet VDMOS models and Mosfet sub-circuits

I built a clone of the Quad 405 back in 1977. ;-)
