I built a linear amp with a pair of 357B tubes and used a power transformer
I got from our local power company. They had the policy of systematically
replacing their power transformers even though they were still working
okay. It put out one heck of a punch. I got across the B+ lead going to the
plate caps of the tubes once, and when I came back around to my senses, I
was on the couch in the living room wondering what happened! It put quite a
hole in my finger.
