Question 3 watt amp

Hey Everyone

Im new here and would like to know if anyone knows where to find the schematics to a 3 watt mono amplifier. I am making a buzzer for something using a buzzing circuit and a 3 watt 1" speaker (from Parts Express). Any help would be great.

Thanks!

Hi,

Easy schematics can be found in the data sheets of several manufacturers, eg:
