How to Make D882 Double Transistor to Audio Amplifier
Hii friend,
Today I am going to make a circuit of an Audio Amplifier using D882 Double transistor.
Let's get started,
Take All Components As Shown Below
Components required -
(1.) Aux cable x1
(2.) Battery - 9V x1
(3.) Transistor - D882 x2
(4.) Battery clipper
(5.) Capacitor - 50V 4.7uf x1
(6.) Speaker
(7.) Resistor - 120K x1
Transistor - D882
This is the pins of this transistor.
Connect Both Transistors
Firstly we have to connect both transistors to each other.
Solder Base Pin of Transistor-1 to Emmiter pin of Transistor-2 as solder in the picture.
Connect 120K Resistor
Next we have to connect 120K resistor to the transistor.
Solder 120K resistor between Collector pin of Transistor-1 to Base Pin of Transistor-2 as you can see in the picture.
Connect 4.7uf Capacitor
Next we have to connect 50V 4.7uf Capacitor to the circuit.
Solder -ve pin of capacitor to Base pin of Transistor-2 as solder in the picture.
Connect Speaker Wire
Solder +ve wire of speaker to Collector pin of Transistor-2 and
Solder -ve wire of speaker to collector pin of Transistor-1 as you can see in the picture.
Connect Battery Clipper Wire
Next Solder +ve wire of battery clipper to Collector pin of Transistor-2 and
Solder -ve wire of battery clipper to emmiter pin of transistor-1 as solder in the picture.
Connect Aux Cable Wire
Now We have to connect wires of the aux cable.
Solder +ve (Left/Right) Wire of aux cable to +ve pin of capacitor and
Solder GND wire of aux cable to emmiter pin of transistor-1 as you can see in the picture.
Last Step
Now audio amplifier circuit is completed so connect battery to the battery clipper and pug-in aux cable to mobile phones and play songs.
This amplifier is working awesome.
Thank you
