Connect the audio input source to one side of the 10k potentiometer. Connect the middle pin (wiper) of the potentiometer through a 0.1 µF capacitor (C2) to Pin 3. Connect Pin 2 to ground.

This circuit requires a heavy-duty transformer (typically a 24V-0-24V toroidal transformer), a high-current diode bridge rectifier, and large smoothing capacitors (at least 10,000 µF per rail) to handle deep bass transients without voltage sag. practical audio amplifier circuit projectspdf

When designing or choosing a circuit, you will encounter different amplifier "classes": Connect the audio input source to one side
