Sometimes you are trying to fix a problem with an amp or other equipment that you're concerned might have a power fault. The worst thing that can happen is that when you turn it on, it immediately pops a fuse - or worse yet a valuable part you've just installed! If you don't have a variac with a current meter so that you can make power on gradual, the next best thing is this widget.
