Transistors TI and T2 form a direct- coupled voltage amplifier. Resistor R6 and diodes D l /D2 determine the quiesc- ent current of the quasi-complementary driver stage T3/T4 and the output stage T5 /T6. The values of resistors R7 and R8 are chosen so that the output transistors are either just biase just cut off depending on the gain of the transistors used. C3, CS, C6 and R3 help to mairitain stabilityd on or
