We will use Class A headphone amplifier circuit that is very good quality sound. Consists low noise Op Amp ICs and 2 transistor as main so have very cheap [...]
Do you love music? Imagine we can build power amplifiers system. Sound good, doesn’t it? Here are many circuits. For example, about Audio amplifiers, bridge amplifier, Using transistor or IC or MOSFET, Mixer, Graphic Equalizer, Preamplifiers. And, Sound generators, tone controls, Melodies, Sirens, Animal sound, effect voices. Even, Burglar alarm, and more. I cannot explain to you all. But sure I do not like to see you miss them.
Want very high impedance preamplifier? We may have many circuits to do. But the FET Preamplifier circuit might be good choice. Because of small, easy, and cheap.
Want a high impedance preamplifier circuit? For a ceramic record player, etc. Make the emitter follower circuit has low noise causes sound concise.
Try medium Impedance Preamplifier circuit using only one transistor. Use a common emitter. Have a lot of circuits use this. try it and learn with fun.
Make the easiest Low impedance input preamplifier circuit using transistor and a few components. With PCB layout and how to reduce hum and low noise output.
Here is the transistor graphic equalizer circuit. Why should make this circuit? We use it for controlling the audio frequency in some kinds of audio frequency responses that are not…
Do you like a transistor? Today I am going to 3 transistors audio amplifier circuits. Why use transistors in the amplifier? Transistors are devices made of semiconductors. It has many…
