This is true.
Now, he does have a good point that the original poster likely doesn't
have the right equipment or skills to diagnose the problem. But....
everybody has to start somewhere and if you don't try you'll never
learn.
I've got a Tektronix 465M o'scope, a digital multimeter, and an ESR
meter.
What more do you need?
Other than what Scott suggested, an isolation transformer would be a good
safety measure. The input circuit typically carries all of the (hazardous)
potential of the wall socket. Phil also said this but the screed had
begun.
