Here the Class A Amplifier with below specification:
The supply voltage can be between 34V and 46V and the quiescent current should be set to 1.7A measured through R25 (a voltage of 0.75V must be measured over R25 for a quiescent current of just under 1.7A).
This schematic is very simple, there is just need 1 active component in each channel (I mean right channel and left channel). So, there are 2 active components for stereo a stereo audio power amplifier.
The schematic originally come from www.circuit-projects.com
Description:
Power supply is a must used circuits. Most of electronic devices which require DC voltage usually need a power supply. Some of them just need original power supply or battery, but some of circuits like Radio transmitter or amplifier needs high current output power supply.
This project is a simple and easy made 5 ampere power supply. To build this circuit, just follow the instruction below:
