You are All Power Amplifiers circuits lists.
Do you love music? Imagine we can build a power amplifier system. Sound good, doesn’t it? Here are many circuits. For example, Audio amplifiers, bridge amplifiers, Using transistors or IC or MOSFET, Mixer, Graphic Equalizer, Preamplifiers. And, Sound generators, tone controls.
See Below on Amplifiers Categories:
The Hi Fi preamplifier circuit project to tune smooth bass-treble, with a very low distortion. Use low noise transistors Frequency response range 20Hz-20KHz [...]
This is Hybrid power amplifier circuit with PCB layout,100W-150W using STK4044XI,STK4046XI,STK4048XI so low THD and low and full protection system [...]
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.
If you are looking for Small PA amplifier circuit using transistors. This may be first choice for you. The output is 100 watts power, very loud and very durable, easy to builds. Is is real?
See STK4231II and build a 2 channel OCL 100W stereo audio amplifier circuit with PCB layout. It's easy, small without adjusting, and cheap.
