There are: Car amplifiers • Mosfet amplifiers • Tone control • Amplifier ICs
• 12V amplifiers • Bridge amplifiers and more :
You finished an audio circuit. But the sound is too weak. Many people use LM386 to increase sound up to a speaker. Why should you do it too? Some said to try it now. But...it is better. If you read LM386 Datasheet before.
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 [...]
Relatively easy to build up to 30W Amp OTL by TDA2030 transistor is packed into this project.the power dissipation of 20W at 8 ohm or 30W at load 4 ohm
Suitable for beginners thought will build the electroacoustics to listen yourself.
This is the Class G 300 watt MOSFET Power amplifier circuit with PCB MOSFET. It have more feature, maximum RMS output power: 200 watts at load 8 ohms or 360 watts at the load 4 ohms.
Good transistor audio amplifier circuit, at 40 watts OCL RMS using 2N3055+MJ2955 is easy to build,and very inexpensive. To use Power Supply +35V -35V 2A.
This is a transistor equalizer circuit. We use it for controlling the audio frequency. Because some kinds of audio frequency response are not smooth. It helps a frequency offset in a tone control…
