Amplifier Diagram

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 …

12-volt amplifier circuit diagram using LA4440: This is a 12-volt amplifier circuit diagram using LA4440. it’s a simple circuit diagram. it’s a stereo amplifier. but now it’s a mono amplifier in bridge mode. in stereo mode, it’s 6+6=12 watts. but in bridge mode 19 watts. we can use 12 volts …

Simple amplifier circuit diagram: This is a Simple amplifier circuit diagram. here used 2 transistors. 2n3055 is an NPN transistor. and Mj2955 is a PNP transistor. both are metal transistors. we also can use another transistor here. Like 2sc5200 or 2sa1943. or C5198 and A1941 also can use here. we …

Speaker protection circuit diagram: This is a Speaker protection circuit diagram for our amplifier. this circuit can save our speaker from unwanted burning. Maximum original amplifier got this circuit with amplifier section or power section. but when we make an amplifier using a local circuit, we have to use this …

Amplifier circuit diagram using TDA7377: TDA7377 is a class-AB audio amplifier. it’s a radio car audio amplifier. normally it’s used in cars. it’s 12 voltage 30+30 watts stereo audio circuit diagram. it’s a dual channel with 60 watts. 30 watts for the left side and another 30 watts for the …

Amplifier circuit diagram using 2n3055 and mj2955: It’s the amplifier circuit diagram using 2n3055 and mj2955. this is PNP and NPN amplifier circuit. in this circuit, we can use 25-0-25 to 50-0-50 voltage. it needs dual voltage. positive negative and ground voltage. here used a 2n3055 transistor for the NPN …
