Introduction: DIY Powerful Amplifier With A1943/C5200

About: I'm from India and love making projects on electronics, specially with arduino. Internet is the only guidance I have and I've been into these since I was 11.

we can make our own DIY Powerful Amplifier with a bass controller in our home, so keep making amplifiers and you have not to pay extra for a good DJ box just make your own.

Step 1: Introduction of C5200&A1943 Transistors

So these Transistors have nothing different characteristics other than the conventional BJTs but they show a high gain so they can be used in high power amplification circuits such as the Powerful Bass controlled Amplifiers which we are going to make.

Please follow the below steps to make your own amplifier and first collect all the components as per the list given below

Step 2: Circuit Diagram

Materials from

A1943 / C5200

100UF 16V Capacitor

50K Volume Control

104PF Capacitor

103PF Capacitor

120K Resistor

1K Resistor

0.4 mm Copper Wire

Step 3: Connect the Coil With the Emitter of the Transistor

Apply seal on the Heat Sink and attach the C5200 Transistor with it and place the transistor side by side.

Connect the Resistor and the Capacitor(C5200) as shown in the figure below and do the connection of the base and the emitter also with a wire in between two transistors(A1943).

Wound a total of 150 Turns and make a solenoid

Then connect the coil with the emitter of the transistor

Step 4: Connect the Negative in the C5200 Emitter Terminal.

Connect the negative in the C5200 Emitter Terminal.

Step 5: ​Connect the Positive Terminal With the S1943 Transistor Emitter.

Connect the Volume controls with the heat sink and the cardboard as shown in the below picture

Connect the 104 PF Capacitors to the volume controls.

Connect the coil and the speaker out end with the Transistor as shown in the figure below.

Step 6: Final Connection

Now this is almost ready and your final connection should look like this , the picture is given below.

And now you can connect the speaker and plug and play the music and you can get the wave of amplification in your own DIY Amplifier.
