Transistor amplifier using sanken transistor:
This is an Amplifier circuit diagram using sanken transistors. It’s an NPN and PNP amplifier. here used 2sa1216 and 2sc2922 transistors. this is a paired transistor. one pair transistor can make 200 watts. that means this 2sc2922 and 2sa1216. 2sc2922 is a positive transistor NPN. and 2sa1216 is a negative transistor PNP. in this circuit we can use a maximum of 70-0-70 voltage and 6 amperes. but we are using 50-0-50 voltage and 6 amperes.
driver transistors, A940 and C2073 are used in this circuit diagram. A940 is a PNP transistor and C2073 is an NPN transistor. all transistors Base Collector and Emitter are the same. 1st is Base 2nd is Collector and 3rd is Emitter. we also can use another transistor following the PNP/NPN and BCE. Here Maximum resistor is 1 watt. 3 watts for sound output. and 2 watts for passing the voltage. All capacitors will be a minimum of 63 voltages. because we use 50-0-50 voltage.
please always use a good quality transformer. good quality diode and good quality capacitors. the voltage capacitor needs 80 voltage and 10000 mfd. we know that Voltage X amperes= watts. so always use a good voltage to get good watts. the main transistor are will be of good quality of transistors. in the market, we can get much quality of transistors. please always try to use good-quality of transistors.
