This is a 20-watt amplifier circuit diagram using the TDA2004 IC. This amplifier can be used in a car. We can use a 12-volt battery to run this board. It’s a mono output board. This IC is stereo, but here the diagram is in bridge mode. The IC is 10 watts + 10 watts in stereo mode. In bridge mode, this IC can make 20 watts of output.

Amplifier circuit diagram:
This is an amplifier circuit diagram using C5198 and A1941. This transistor can make 100 watts of output. We can use a maximum 50-0-50 voltage in this circuit. Here we are using 35-0-35 voltage and 3 amperes. It’s a mono audio board. For stereo, we have to use a dual board. We can also use other transistors. positive, negative, and ground voltage. must use a strong voltage and amperes to get a good output watts.

how to make a bass tone circuit?:
This circuit diagram uses one transistor C828. Here used 4 volumes were used. volume, bass, and high, and tone. This circuit is one of the best bass tone control circuits. It runs on 12 volts. Every amplifier needs this circuit to control the sound.
