This is a 200W power amplifier circuit project. The circuit features high power, good definition and very low noise. It delivers about 200 watts in 4 ohms loudspeaker: a 4 ohm speaker or two pieces of 8 ohm speakers in parallel. This 200W power amplifier using the complementary transistors of 2SC5200 and 2SA1943 as the main parts.
If you use it with only one 8 ohm speaker, it will deliver a power of 100w. The printed circuit board has the following measures: 13.6 cm x 13.9 single sided. The power supply used for this circuit is a symmetrical type which capable to delivers ± 50 VDC by 4 Amperes to the circuit. The power supply schematic is included in this board.
