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.
Connector J1 is for audio signal input, J2 Power Amplifier Output, J3 -VDC, J4 +VDC, J5 GND.
This Super Simple Power Amplifier 200W it can work with Power Supply minimum 25VDC up to 45VDC. It can deliver maximum output power up to 200W with 8 Ohm impedance output load.
Below the PCB Layout Super simple power amplifier in 2 Layout Gerber view.
