This symmetrical unregulated power supply is used to feed the audio amplifier based on LM1875 amplifier module National Semiconductor. With symmetrical 30V DC source the amplifier capable of delivering up to 30W of power using 8 ohm load.
The Power supply for high-end audio recommended for work with with your hi-fi amps shown in the project is actually very simple, without any good skill level is needed to create (or even design) one. There are several factors you should be cautious with, like the routing with higher current leads, however, these can be completed.
Form of the following Power supply for high-end audio is simple. A single four Amper fuse is required to protect the transformer and 2 LEDs in the end on this circuit are utilized to show electrical power condition Off and on.
