Hi Jeff, I didn't start out with "Violet Ray" machines but I did a lot of
experimenting with them and quite a collector of them until I started
unloading most of my collection in the late 1980's. I certainly would NOT
suggest that anyone allow kids to play with the "Violet Ray" units
because the way they are made there is a direct path back to the mains!
Thus representing a serious shock hazard! The "Violet Ray" machines are
almost identical in construction to the current day vacuum testers and
both are novel in that they don't use ANY high voltage transformer but
instead use the counter E.M.F. of an inductor to generate the high
voltage for the primary circuit. This is some times referred to as
"kicker coil"
driven Tesla coils.
