Yes, and no one has mentioned oil furnace ignition transformers, which are
more common and less expensive, IMHO.
11,000V, center tap grounded to frame, so don't get shocked.
(do I have to say this? What's
wrong with people these days?)
Maybe 50mA, probably more like 10mA. I built a ladder out of one of these
when I was a kid. I used coat hangers soldered directly into the outputs
using a 100W iron. Interestingly, the flame would stop to burn through what-
ever was inserted before continuing up. It would burn through pencils this
way. I didn't have the guts to put my finger in there. Amazingly, I didn't
get shocked by it, though I did from most of the other things I played with
such as old tube radios. Later in life I had to work on industrial
induction heating equipment that always leaked water. I had to defeat the
safety interlocks and stand in the water while sticking scope and meter
probes inside. I didn't get killed doing that either.
