This is a mini amplifier circuit diagram using 2SC5200 and 2SA1943 transistors. It’s a mono board. It’s a PNP and an NPN amplifier board. We can use any PNP and NPN transistors. like c5198 and a1941. 2SC2922 and 2SA1216. We can use 20-0-20 voltage to 50-0-50 voltage. positive, negative, and ground voltage.  The transistor 2SC2922: … Continue reading Mini amplifier circuit diagram using 2sc5200 and 2sa1943
