How to make a small amplifier circuit: This is a small amplifier circuit diagram. it’s 10 watts. this circuit run with 12 voltage to 15 voltage. this circuit used TDA2003. this is the mono-circuit diagram. if we need stereo then we have to use a dual circuit. One circuit for …

Microphone circuit diagram: This is the microphone circuit diagram. the maximum amplifier needs a microphone. without a microphone audio are nothing. for recording any audio we need a microphone. we hear sound this sound recorded using this type of circuit. this is so easy circuit. here used 3.7-volt battery.    …

5 voltage amplifier circuit: This is 5 voltage amplifier circuit diagram. it’s a 0.25 to 1 watt 4 ohms diagram. we can use 4 voltage to 12 voltage. this is a mono diagram. here we can use 2 watts speaker. if we want to make a stereo amplifier, we have …

Subwoofer amplifier circuit: This is the Subwoofer amplifier circuit diagram. this circuit is for the bass amplifier. when we want to make a sub amplifier then we need this circuit to make only bass. this circuit is used as a pre-amplifier. it’s made only of bass. low part only. here …

How to make a small amplifier: This is the circuit diagram for 20watts using tda2030. These chips run a 4Ω speaker at 18W or an 8Ω speaker at 14W. this circuit diagram runs with positive negative and ground voltage. we can use a maximum of 15-0-15 voltage. 12-0-12 voltage is …

Headphone amplifier: This is a Headphone amplifier circuit diagram. sometimes we need an amplifier for our headphones because of the low sound volume. some tv has no headphone output line. there have only one audio pre-out for another amplifier. there we need this circuit diagram. this circuit runs with 5 …

Transistor amplifier circuit diagram: This is a transistor amplifier circuit diagram. it’s the basic circuit. transistor makes small to big. small sound to a big sound. transistor only makes small to big. there are two types of transistors. PNP transistors and NPN transistors. The PNP transistor is a negative transistor …

Push-pull amplifier: This is push pull amplifier circuit diagram. input and output base amplifier. here used 2 transformers. One is an input transformer and the other is an output transformer. used 12 voltage only. we can use the battery for this amplifier.  here used PNP transistors. 2n2955 is the best …

Bass treble circuit diagram: This is a Bass treble circuit diagram. I always need this circuit to make an amplifier. if we want to make a good-quality of sound then we need this circuit. every amplifier makes a raw sound. amplifier only makes the sound lower to higher. like small …
