Basic Amplifier Circuit Diagram. You can also make the circuit in the breadboard. Here are some pictures for making the circuit.

When a weak input signal is given to the base of the transistor as shown in the figure a small amount of base current flows. Using transistors mosfet ic on a lot types. Here are some pictures for making the circuit.

In this circuit we can use 10 transistors.

Ttc5200 is npn transistor and tta1943 is pnp transistor. If you need exactly 6 you can play a round with the resistance on the input. But there may be loose connection so i have directly soldered all components. Many power amplifier circuit diagram with pcb layout.
