This is a Stereo amplifier circuit board using 2SC5200 and 2SA1943. It’s a stereo diagram. We can get a 200W+200W output. here can use 25-0-25 voltage to 50-0-50 voltage. dual voltage needs. positive, negative, and ground voltage. PNP and NPN transistor diagram. The output watts depend on the voltage.  Details about 2SC5200  2sc5200 Polarity is … Continue reading Stereo amplifier circuit board using 2sc5200 and 2sa1943
