A 200W power amplifier circuit diagram sharing

This is a 200W power amplifier circuit project. The circuit has the characteristics of high power, good clarity and low noise. It provides about 200 watts of power in a 4-ohm speaker: one 4-ohm speaker or two 8-ohm speakers in parallel. This 200W power amplifier uses complementary triodes of 2SC5200 and 2SA1943 as the main components.

If you use only one 8 ohm speaker it will provide 100 watts of power. The PCB has the following dimensions: 13.6cmx13.9 single sided. The power supply used in this circuit is a symmetrical type capable of providing ±50VDCx4 amps to the circuit. The board contains the power supply schematic.
