Build a soft start circuit for your audio amplifier
The current surge demanded at power-on by a circuit presenting a large capacitive load to the power supply can destroy the power supply or trigger its short circuit protection. In both cases the result is the same: the circuit will not start. A solution is to insert a soft-start circuit to control the inrush current. This soft-start circuit with many additional features was designed to protect an audio amplifier and you can build it too.
