MOTM

I have an old Kenwood TS-820 ham radio that has about 900V inside it on the
output tubes.  I had to check the supply voltages one time and it took me
quite a while just to get up the nerve to do it (and make sure my hand -
other was in back pocket - wasn't shaking at the time!).  :-)

As a side note... when changing the heating element on a 220V water
heater... turn off the circuit breaker FIRST before sticking a wrench in
there!  Duh!  Don't ask.
