Aug 23, 2017 at 10:14 comment added Marko Buršič You have messed up the terms common collector/emitter and impedance claim. Even if you rearrange the circuit to output a sine, this audio amp would be good to drive a PC speaker, surely not to listen the music.
Aug 23, 2017 at 10:08 comment added JIm Dearden Problems? - Q2 is a small signal bjt (not enough current drive capability), R7 is too high to discharge C4 for symmetrical output, C4 is too small for an 8 Ohm load. Where to start - try replacing Q2 with a power Darlington and go from there.
