Circuit Power Amplifier using IC741 for buffer stage, and final stage using Transistor MJ2955 and MJ3055 as much 3 set transistor.
Output power about 400Watt RMS at supply voltage 34VDC assymetric. See circuit schematic power amplifier below :
|Schematic created on EasyEDA project if you have account EasyEDA|
you can see clearly schematic and edit it here.
This power amplifier is simple to make it, you can apply power amp at home audio . Audio in is buffered by ic 741 , as a op-amp ic , but the driver i use it mje340 and mje 350 , in PCB layout using BD139 and BD140 you can change it. For better quality power amplifier ,Capacitor using 50V. Resistor using 1/2 Watt if no labeled. if you want to assemble it you can see this pcb layout power amplifier :
