i had tried to make an AC buffer so i used the B class push pull circuit. but i didn't find a crossover distortion when i coupled both transistor (NPN & PNP) straightly. theorytically, it should be a distortion there because of forward biasing emitter diode (in both transistor). i used 2N3904 and 2N3906, then i put two 330 ohm resistors on each emitter tap. i got a pure sine wave on 40 KHz. i dont know why there's no distortion, but i should explain it on my final project book.
