Bench Audio Amplifier
This is a simple audio amplifier project suitable for the workbench. It has it’s own internal mains PSU but this can be substituted for an external PSU for those constructions not comfortable working with mains electricity. It provides a pre-amplifier module, three-band equaliser and has output short-circuit and thermal protection and a maximum 5 watts…
