This article talk about Class A amplifier. It is good for small speaker or headphone. Amplifier make sound more loud. This Class A Amplifier Circuit uses near 20 milliamp power so it good for low power thing. We show in this post how to make it using Q1 and Q2 transistor and this transistor work […]

10 Watt Amplifier Circuit using IC TDA2003
To make one cool and 10 Watt Amplifier Circuit using IC TDA2003 is too not hard. This circuit is good for small project for kids or for someone new in electronics. It is quite simple and very easy to build. TDA2004 chip is good and already have many parts inside for good sound. We only […]
Simple LM386 Audio Amplifier Circuit
In this Simple LM386 Audio Amplifier Circuit we use one popular chip called LM386 to make small sound amplifier circuit. It does not cost much and easy to make and can make speaker or music player sound louder. It is not very powerful for big show but good for small projects. And also is good […]
Small Amplifier Circuit using Transistors
This is one Small Amplifier Circuit using Transistors which work like basic audio amplifier. It makes weak sound signal more strong so sound come better like in car radios. Now lets see how this circuit is build and how it work. Circuit Working: Parts List: Category Component Quantity Resistors 100k 1/4W CFR 1 1k 1/4W […]
Simple MIC Preamplifier Circuit
This is small and simple MIC preamplifier circuit using op-amp IC LM358 and it uses op-amp to make weak sound from MIC more strong, so it boosts low audio signal into stronger one. Also, the circuit is good to record voice or connect to speaker and it is easy to make with not many parts. […]
IC 555 Amplifier Circuit
The IC 555 chip is very useful in many electronic works, but this project is not same like normal timing circuits. Here, we are making IC 555 Amplifier Circuit which uses microphone. At first, microphone take the sound and then one small transistor give little power to sound like small switch. At last, IC 555 […]
