SEE! TDA2030 Bridge amplifier circuit diagram with PCB layout, output of 35 watts at 8 ohms speaker. It use Dual 15V DC power supply at 2A.
This is Mini 40 watt audio car amplifier circuit using HA13001 on BCL system, so small and easy with PCB layout and can all 12V-14V power supply
This is gainclone amplifier circuit, project as stereo 40W-56 watt main amplifer use LM3875. It easy to build by 2 ICs ,more a few parts ,without any set...[...]
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.[...]
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.
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.
The IC-TDA2009 amplifier circuit on stereo 10W+10W IC is to qualify from the power supply 8-24V, the current maximum of 1-2A. and 24V load 4 ohms [...]
