how to make amplifier using battery

2 transistor amplifier diagram using the battery:

This is 2 transistor amplifier diagram. we also can use the battery in this circuit. this circuit can run with 24 voltage to 36 voltage. for 24 voltage we have to use 2 batteries and for 36 voltage we have to use 3 battery. but here we are using 35 voltage 3 amperes transformer. 


Here used,

2n3773 transistor. It’s 16 A and 140 voltage.

It’s an NPN transistor,  Bipolar Power Transistor. it’s a 150 Watts transistor at 100 voltages. this is a mono amplifier circuit diagram. if we want to make a stereo amplifier then we have to use 2 circuits for stereo. one for the left speaker another one for the right speaker.

This is the diagram:
