This is a 2sc5200 2sa1943 amplifier board 200 Watts. It’s can make 200 watts maximum because it’s 4 transistor amplifier, circuit board. the watts depend on the transformer voltage and amperes. We know that Voltage X Amperes= Watts.
It’s NPN Epitaxial Silicon Transistor
1. High-Fidelity Audio Output Amplifier
Features about 2sc5200
1. High Current Capability: Ic = 15A.
2. High Power Dissipation: 150watts.
3. High Frequency: 30MHz.
4. High Voltage: VCEO=230V
2sc5200 and 2sa1943 transistors can take DC 1.3 amperes. here in this circuit, we can use 40-0-40 voltage and 5 amperes. then we can get watts. voltage X ampere= watts. 40X5=200 Watts.
Here in this circuit needs dual power. Positive Negative and Ground voltage. 2sc5200 is a positive transistor and 2sa1943 is the negative transistor.
