This is one of the worst examples of mis-information I have ever seen.
What makes this kind of comment so dangerous is that someone might
actually follow Rich's advice and kill someone.
Comparing a heart defib to a HV amateur amplifier supply is like comparing
a OSHA approved climbing harness to a hank of clothesline from Wal-Mart
for safe tower climbing.
Yes, heart Defibs do discharge a tremendous amount of energy in a effort
to re-start a heart.....trying to do the same with a HV PS will most
likely kill them AND you.
