This is a small Stereo amplifier 3W + 3W using BA5406-IC. It use 12V power supply as source of this project. and use a few part so easy to build.
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.
This is a bass booster circuit that use transistors as base. It is designed to increase a low frequency of audio on cheaper than ICs or normally circuit.
This 100W amplifier circuit by transistors, but very well OCL amplifier schematic.Use transistor MJ15003,MJ15004 as main. Power supply +38V 0 -38V 3A. [...]
See simple intercom circuit using transistors and a few parts. So easy build and cheaper than ICs. For a small home and learning.
Simple electronic drum circuit project is an Instrument of this era really, various sound effects and many others, using digital IC and more
I recommend you to make a Simple speaker delay circuit. Imagine you finished a normally OCL power amplifier. Every time you turn on within the first 3 seconds. You may…
This is 2 watts + 2 watts Stereo small LM386 amplifier x3 ICs. It is cheap and easy to builds for BCL amplifier,mobile,MP3 player using 6V battery (AA x 4) [...]
