This is a 4 transistor audio amplifier circuit. Which is a 4-transistors complementary push-pull amplifier, that shows the basics of audio amplifier design. This circuit saving on battery current, which is quite low with middle volume, rising to 25 -30mA as a volume is increased. This gives us a 250 mW amplifier

Week #1: Audio amplifier Week #2: Microphone circuit The audio amplifier project is more difficult and time-consuming than the microphone pre-amp, so part of week #2 may be used to finish the audio amp. All breadboarding and testing can and should be done in lab. Soldering and hardwiring can and should be done outside lab.
100W Audio Amplifier - CircuitLib

This is a nice final audio amplifier to build it and have fun. The amplifier is able to drive up to 100W to a 4 Ohm load or up to 70W to an 8 Ohm load. The total distortion is less than 0.1% (even in high frequencies). The circuit uses ordinary electronic components and the amplifier has DC coupled output, for best performance even at low ...
DIY Audio Projects Forum • TDA2030 based amp for 4 ohm speaker
https://diyaudioprojects.com/Forum/viewtopic.php?t=2996
hi all, i want to build a TDA2030 based amp for 4 ohm speaker. i am planning to use the typical ckt given in the datasheet of TDA2030. i want to know whether its better to go for split supply or single supply? which one gives good performance? also if i chose SMPS power supply for single supply design, how much current would be required? also i am looking for …

This amp can deliver about 50W into a 8-ohm speaker and 100W into a 4-ohm speaker. This is a stereo amplifier and therefore 4 LM3886s are used. The LM3886 circuit is in a non-inverted configuration, so the input impedance is determined by the input resistor R1, i.e. 47k.
40 Watt Audio Amplifier Circuit Diagram using TDA2040 …
https://circuitdigest.com/electronic-circuits/40w-audio-amplifier-circuit-diagram-using-tda2040
The schematic is 40 watt audio amplifier pretty simple; the TDA2040 is amplifying the signal and providing 25Watt RMS wattage. Additional power amplification is done using BD711 and BD712 transistor pairs.Input capacitor 470nF is the DC blocking capacitor which will only allow the AC signal to pass.
