Increase emitter cap to 1mF and the base cap to 100uF. Other than that, the circuit is correct

Buggzy, are you sure about your recommendation? Suppose its a audio amp, why this ultra big caps you recommend? A gain of more than 20dB doesn't make sense for a single BJT stage. And 100uF base to 1mF emitter is a good way to kill the BJT. Check this http://everycircuit.com/circuit/4746916954374144

Yeah if it's an audio amp the gain is high, but i just assumed the gain was supposed to be high.
