Amplifier Diagram

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 …
