Amplifier Diagram Simple. So there are some disadvantages to the circuit. There is no noise cancellation in the circuit.

There is no noise cancellation in the circuit. So you will find extra humming noise in the amplifier. We can use 12 voltage to 24 voltage to this simple amplifier.

Here are the full schematics of a simple audio amplifier.

We can use 12 voltage to 24 voltage to this simple amplifier. You can choose 0 5w to 1 200w. That s why this circuit is not for practical application purposes. You can also make a 5w mono amplifier out of it.
