Producing 2nd harmonic distortion by an asymmetrical power supply?

At your risk.


How would for example BD139, BD140 complimentary pair sound with a power supply of -9V 0 11V.


In class A (electrons flowing all the time) through devices.


A DC offset at output would make electrons flow all the time through speaker as well.


Asymmetrical overload creates 2nd harmonic distortion or othe even order overtones. [Terman]


But mabe that's enough with push pull as a single ended class A amplifier sounds great, can produce even order overtones and can be made with just one transistor. See for example Pleiades 2N3055 or Pleiades BD149


At your risk.
