I have built a 10W Stereo Amplifier With Speakers. This amplifier can take a low-level sound source like a phone or music player and amplify it to power connected speakers to generate more power and better sound. The TDA2005 IC is the main part of the circuit, and it performs the amplifying function. The resistors, capacitors, and diodes provide signal stability and protection.
I followed the circuit diagram carefully and bored the PCB for components. Then I put the resistors, capacitors, diodes, and the IC on the board and soldered all of them to secure and stable connections. After connecting all the parts together, I put the circuit to work connecting it to a power supply, an audio input, and the speakers. In testing, I checked everything worked as expected and tweaked if needed.
