Jim, I would say he had many other problems also. Perhaps he could get a voltage doubler and start a jacob's ladder using his body and the scope as the ladder?? By the way, a good example of high voltage stupidity: http://www.drmegavolt.com/underpages/warning.asp or got to www.drmegavolt.com for his main page. What are you doing us so late? I am going to bed now...
