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.

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

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

Next Connect 1K resistor to the transistors

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

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

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.

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.

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.

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
