This is a very poor design. T1 and T2 have no bias stabelization. They depend on the current gain of the transistor being less than 100. If the gain is more than 100, the transistor saturates and and the gain becomes very low. T3 is not stabelized either but the current is limited by the emitter resistor. The sound quality will be poor because T3 is operating in a non-linear way.
