The audio amplifier was invented in 1909 by Lee De Forest when he invented the triode vacuum tube (or "valve" in British English). The triode was a three terminal device with a control grid that can modulate the flow of electrons from the filament to the plate. The triode vacuum amplifier was used to make the first AM radio. Early audio power amplifiers were based on vacuum tubes.

Power MOSFETs are emerging as the device of choice for high-quality power amplifiers because of their speed, reduced need for protection, and falling cost. A low-distortion power amplifier design is presented which includes output stage error correction to reduce the effect of transconductance droop in the crossover region and thus allow

Vertical power MOSFETs (and similar technologies, such as PI and trench types like Toshiba J200/K1530) tend to have a 'sweet spot' where the capacitance, gm and current are sensible enough tp get good performance in audio - usually this happens in MOSFETs with Vdsmax between 100 and 300V - usually on the lower end of this range for P channel …

The only change that is needed is to trim the MOSFET bias pot! With the full supply voltage of ±70V (which must not be exceeded!), continuous ('RMS') power is around 180W into 8 ohms, or 250W into 4ohms. Short term (or 'music') power is typically about 240W into 8 …
