Googling electrocution by consumer devices is per year in the United states: 1 person per three million.
So for 300,000,000 that is about 100 folks die PER YEAR in the united states from electrocution from home apliances or electronics.
The greatest percent of those are from appliances, and power tools, and mostly men.
No percentage is given that I can find for folks messing with thier stereo equipment.
And those would all be for guys repairing or putzing with the insides of thier stuff anyway.
The risk is just not present for the non intrusive (not inside the equuipment) audiophile.
And if anyone WAS killed or even harmed.. i am CERTAIN it would end up on sites like this by word of mouth, or on Yahoo: "Two six year olds electrocuted by dads stereo" or some such blather...
Even Herman admits to getting a few 'zaps' as a kid (so did I) So what?
Making a mountain out of a molehill is what this thread is about.
And YES I am saying it is nonsense to be concerned beyond such things as stopping for stop signs, or red lights, speeding, etc. Even slipping in the bathtub is as lethal (per percentage).
So unless you are planning to stick two screwdrivers into the wall outlet, and then bit down on them.. i would not get too worried.
So gimme a break on getting electrocuted by your stereo.
