TSP #108 - Teardown Repair of an Agilent E3632A DC Power Supply

In this episode Shahriar Rosanah investigate an Agilent power supply which does not appear to power on. It can be quickly observed that the fuse has failed on the unit. Using an isolation transformer a small amount of AC voltage is applied to the unit after the fuse replacement. It is clear that a short is present somewhere in the instrument since even at 10V AC the instrument consumes more than 1A. After separating the internal transformer from the main PCB, the high current consumption is eliminated.
