Power Amplifier 400 Watt using IC741 and MJ2955/3055

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 :
Circuit schematic Power Amplifier 400 Watt using IC741 and MJ2955/3055
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 :
