Principle of a simple AB power amplifier

The amplification is given by the feedback of 2 resistors. The cross-current can be adjusted with the 600k and the 1M resistors.
The output stage does not require any complementary transistors!
(In real life, the circuit still has to be provided with various current limitations, since excessive power is lost at certain components when overdriven).
