Audio Circuits

If you want build hi-fi power amplifier about 30watt to 50Watt or 75 watt. Recommend use TDA2050 below, builds by the integrated circuit and PCB layout.[…] Read more

Do you want low-frequency class B power amplifier? See TDA2020 may be one of choice that you not should miss. Gives 20W to 80W with helping from a transistor. Read more

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. Read more

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. Read more

This 100W amplifier circuit by transistors, but very well OCL amplifier schematic.Use transistor MJ15003,MJ15004 as main. Power supply +38V 0 -38V 3A. […] Read more
