Dual Output Power Supply +/-53V / 3A based on Transistors

Dual Output Power Supply +/-53V / 3A based on Transistors
This is the circuit diagram of dual output power supply +/-53V / 3A based on transistors. This circuit has been designed for audio amplifier power supply requires a symmetrical + / -53 V (+ / -56 V maximum). The role of the circuit part presented here is to lower the voltage of both positive and negative lines of + / -65 V for non-hazardous + / -53 V for the amplifier, while allowing the current to 3 A in

± 60 Volt Switching Power Supply for PA

± 60 Volt Switching Power Supply for PA
The main part of any amplifier is the power supply. It is clear that to obtain a high output 12-volt battery is not enough. Therefore, we must first create a voltage converter, which enables a bipolar supply +-60V with a capacity of no less than 400W. Digging on the forum found a fairly simple and relatively good scheme.

Unregulated Power supply for high-end audio amplifier with two polarity

Unregulated Power supply for high-end audio amplifier with two polarity
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 Ampere fuse is required to protect the transformer and
