How to Make 3055 Transistor to Audio Amplifier

About: Share diy projects to those who have the same hobby with me

Hii friend,

Today I am going to make an audio amplifier using 3055 Metal Transistor.

Let's get started,

Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Take All Componenets As Shown Below

Components required -

(1.) Transistor - 3055 x1 (Metal Transistor)

(2.) Capacitor - 25V 100uf x1

(3.) Resistor - 1K x1

(4.) Aux cable

(5.) Battery - 9V

(6.) Speaker

(7.) Battery clipper

Step 2: Transistor - 3055

This picture shows the pinouts of metal transistor 3055.

Step 3: Connect 1K Resistor

Solder 1K Resistor between Base and collector of the Transistor as solder in the picture.

Step 4: Connect Capacitor

Next we have to solder +ve pin of capacitor to Base pin of transistor as you can see in the picture.

Step 5: Connect Aux Cable

Next Solder Left/Right wire of aux cable to -ve pin of capacitor and

Solder GND wire of aux cable to Emmiter pin of the transistor.

Step 6: Connect Speaker Wire

Solder -ve wire of speaker to Collector of 3055 transitor as solder in the picture.

Step 7: Connect Battery Clipper Wire

Now we have to connect battery clipper wire to the circuit.

Solder +ve wire of battery clipper to +ve wire of speaker and

Solder -ve wire of battery clipper to emmiter pin of the transistor as you can see in the picture.

Step 8: Circuit Is Completed

Now our audio amplifier circuit is completed so connect battery to the battery clipper and

Plug-in aux cable to mabile phone and play music.

This type we can make an audio amplifier circuit using 3055 metal transistor.

Thank you
