Pre-amplifier circuit diagram:
This is a pre-amplifier circuit diagram. Every amplifier needs this type of circuit diagram. This circuit makes the sound good. It has one main volume, a low part, a mid-range, and a high. This diagram runs using 12-voltage only.

100 watt amplifier board
This is a 100-watt amplifier board. it’s a mono-circuit diagram. TDA7294 is a popular IC. It can make 100 watts maximum in bridge mode. we can use single voltage Ac 15 volt to 28 volt. the output will depend on voltage. strong voltage can make a strong watt. we have to use a good-quality heatsink for the IC. because this circuit makes it so hot in bridge mode.
