50W Audio Amplifier Circuit
Here the 50W audio amplifier circuit diagram. The amplifier is based ICL8063. This a good amplifier circuit which is easy enough to built.. This circuit can be connected by radio, TV, stereo or other devices. The circuit is also featured with inputs for the record player, guitar, microphone, and others. If you add low pass filter at the input, it will work like a mini-subwoofer. Circuit scheme presented will guide you in 50W amplifier construction, good luck. The power supply is splitted type, already added on above circuit diagram.
