Basics of troubleshooting power supplies

When a piece of equipment turns up completely dead, one of the first things to look at is the power supply. If using an oscilloscope for this sort of troubleshooting, it should be a hand-held, battery-powered instrument isolated from ground, at least at the outset. The reason is there may be internal voltages that are referenced to but float …
