Make A Hi-Fi Stereo Audio Amplifier Using LA4601


Here is a simple 4W audio stereo power amplifier using a ten-pin LA4601 IC. Only a few passive components, including ceramic and electrolytic capacitors, are used in this circuit. The 9V DC power supply helps obtain 4W stereo output. The authors’ prototype of the hi-fi stereo audio amplifier is shown in Fig. 1. Its circuit […]
