#134: Teardown of failed power supply – bad capacitor

This short video shows the teardown of a small, cheap linear power supply that failed after a few minutes of being plugged in for the first time.

The video shows opening the supply up, and looking at what failed – a bad capacitor, bulged and high ESR. A video describing my ESR meter can be found here:
