Input is around 50mV AC then amplifier it with an inverting op amp then got its maximum current boosted by a transistor output stage

There might be some distortion to the output current as there is obviously a voltage drop in those transistors that pretty much wiped out the low voltage signal

very messy layout, and a lot tonchangento make it full symetric. You mixed somehow a single supply with symetric supply version. Check this http://everycircuit.com/circuit/5471618974089216
