13002 Double Transistor Amplifier

DESCRIPTION

Hii friend

Music feel us comfortable and we listen music for entertainment purpose.But if sound of your mobile phone is not high then you would not be like to listen music.So Today I am going to make an audio Amplifier using 13002 double transistor.This transistor we can get from old cfl.If cfl is not working then we can remove transistor from cfl.

Let's get started,

Description:

Take All Materials As Shown Below
3 More Images

Materials required -

(1.) Transistor - 13002 x2

(2.) Capacitor - 25V 100uf x1

(3.) Resistor - 1K x1

(4.) Jumper wire x1

(5.) Battery - 9V x1

(6.) Battery clipper x1

(7.) Aux cable x1

Description:

About 13002 Transistor -

1} Pin-1 of this transistor is Base,

2} Pin-2 of this transistor is Collector and

3} Pin-3 of this transistor is Emmiter as it is shown in the picture.

Description:

Firstly we have to connect both transistors as shown in the picture -

Solder Emmiter of transistor-1 to the Base of transistor-2.

Description:

Next Connect 1K resistor to the transistors

Solder 1K resistor to Base and collector of transistor-1 as you can see in the picture.

Description:

Solder +ve wire of capacitor to the base pin of transistor-1 as solder in the picture.

Description:

Next we have to connect jumper wire -

Connect Collector pin of transistor-1 to the collector pin of transistor-2 as connected in the picture.

Description:

Next we have to connect aux cable wire -

Solder Left/Right (+) wire of aux cable to the -ve of capacitor and

-ve wire of aux cable to the emmiter pin of transistor-2 as you can see in the picture.

Description:

Now connect +ve wire of battery clipper to +ve wire of speaker,

connect -ve wire of battery clipper to emmiter of the transistor-2 and connect

-ve wire of speaker to collector of the transistor-1 as you can see in the picture.

Description:

Now the circuit of 13002 double transistor audio amplifier is ready.

HOW TO USE IT -

Connect battery to the battery clipper and Plug aux cable to mobile phone/laptop/tab/......

and play song.

Now enjoy the music
