How to make STEREO amplifiers with ATX PC power parts | Class A

Welcome to my channel: Share Tech Creative The ingredients need to be prepared NPN C945 transistors x 2 You try to find two identical NPN transistors! This is all in one ATX PC power adapter Get two identical 13007 MOSFETs You should choose bigger aluminum heatsink, to dissipate both resistors 10R / 10W x 2 resistor Adhesive resistor to aluminum radiator It is possible to use another aluminum plate to heat the resistor ... because it is very hot ...!!! Connect two resistors pins The schematic diagram for this amplifier circuit Sinusoidal filter roll Connect the two ends of the resistor Insulated pipe Connect two resistance pins to the C pin of the two transistors C945 transistor Connect pins E to B and pins C to C of the two transistors Resistor 33k Connect with B-C pin of transistor C 945 Wooden or plastic plate Clamping station amplifier 4 Connect two GND pins (grounded) connect left and right channels 1000mf / 16v capacitor pair Connect with pin C of 13007 two transistors Connect left channel, right channel to the speaker station Two capacitors 1000mf / 10v Two resistors 0.47 / 5w Connect two resistors to the E pin of two 13007 transistors with GND Connect two capacitors to the E pin of two 13007 transistors with GND, in parallel with the two resistors. General GND wiring Two potentiometers 50k Connect pin 3 of two potentiometers with GND 1000mf / 10v capacitor Connect with pins B of two transistors 13007 ... ... with legs 2 of the two presses 3.5mm jack cable Connect to pin 1 of the two pressure 5.5mm female jack connecting to 12v DC power supply Supply 12v to the original circuit Proceed to checkout left speaker right speaker Both speakers left and right Thank you for watching videos Click Like and Subscribe channel if you see good video ... bye and see you again
