Super OCL Power Amplifier 500W DEF

Super OCL power amplifier with double emitter follower on final transistor it can deliver power output more stability, and this version I have added capacitor decoupling on the final transistor. This amplifier is a wide power supply range minimum power supply voltage 25VDC to 90VDC symmetrical power supply, and minimum current 5Ampere. Output maximum of this amp up to 500W.

Below the schematic and PCB Layout design, you can download this project and PCB Gerber file at the end of the post.

The final transistor can be using: 2SC5200/2SA1943, NJW0302/NJW0281G, MJL21193/MJL21194, C6011, 2151
Driver transistor can be using: B507/D313, C5171/A1930, MJE15032/MJE15033, C4793/A1837

The final transistor is upgradable for more high power output
