IC Power Amplifier with OT Trafo

This amplifier circuit uses IC and Trafo OT as an additional amplifier in the output. You can use the transformer output transformer-old has not used but still in good condition, you can use it in this circuit. For this amplifier IC used is M51503L, this ic has a voltage limit of up to 7 volts only and a minimum of the incoming voltage about 2 volts. Actual output issued from the IC is 0.2 Watts, but once applied to the circuit maximum output of about 5.3 Watts.
