200W Super Simple Power Amplifier

Hello guys, this time I will share a circuit of the power amplifier that is very simple but still put forward the sound quality and the power is quite large. This is a super simple power amplifier 200Watt output power that driven by final transistor 2SA1943 and 2SC5200 1 set. Power amplifier type is OCL with Class AB system, and include bias trimpot for setting DC Output power amplifier.

Below is the super simple power amplifier circuit diagram.
