Dual Polarity Unregulated PSU For High-End Audio AmpsA power supply suitable for use with the hi-fi amplifiers presented in the predeeding project is perfectly simple, and no great skill is required to build (or design) one. There are a few things one should be careful with, such as the routing of high current leads, but these are easily accomplished. Design of this power supply is very simple. A 4 ampere fuse is used to protect the transformer and two LEDs at the end of this circuit are used to indicate power state On and Off. At the ouptut there are 6 capacitors used you can reduce the quantity of these filter capacitors to 2 or according to your own choice.
