Make Your Own Simple Stereo Amplifier

The Make Your Own Simple Stereo Amplifier project centers around the CD6283 audio amplifier integrated circuit (IC), which serves as the core dual-channel amplification engine. Audio input signals enter the circuit through connectors such as CON1, CON2, or CON3, passing through optional 22-kilo-ohm potentiometers that act as volume controls by attenuating the signal level before amplification. Capacitors—including designated components like C2, C3, C9, and C10—are strategically placed throughout the circuit for power supply decoupling, noise filtering, and DC blocking to ensure clean signal propagation between stages. Once processed, the CD6283 IC boosts the audio signals to drive a pair of 4-ohm, 4-watt speakers for the left and right stereo channels. The entire circuit is powered by a 6-12V power supply or battery, connected to either a custom PCB or a veroboard, providing the necessary voltage rails to deliver approximately 4.6 watts of power per channel to the output speakers.
