I am trying to know what is the black circular component stacked in front of the switch and adjacent to the large capacitor in this circuit board.
I am not talking about the transistor with the heat sink. I am talking about the circular black component.
This thing has 4 pins in the bottom.

This element is a bridge rectifier. The two oposite pins are AC input (designated with ~ ) and the other two are DC output (designated with + and - ).
