Amplifiers with power above a dozen or so watts require a power supply supplying two voltages (i.e., symmetrical voltage). The presented system is a simple power supply that allows you to work with audio amplifiers up to 100W. The module can be a complement to the self-built audio system. It allows you to make a non-stabilized power supply with a maximum output current of up to 6A.

Attention! Electrolytic capacitors connected to a voltage higher than their rated voltage and reversed, may explode, posing a serious health risk! There are dangerous voltages for health and life in the power supply, which may persist for a long time after the power supply has been disconnected. Before connecting the amplifier to the power supply, make sure that the capacitors C5 ... C10 are discharged.
