Dear M & L Nunas:
After reading your techie version of the pulse-circuit ("Pulsar" was
an attempt at humour, but no-one seems to want to pick on me today),
I retract my above statement. I thank you for the explanation - I
actually understand this (used to be a mainframe computer techie).
Now if the output is simply a short duration spike of about 60 volts,
why not take line voltage A/C through a limiting resistor and an SCR
with a very short trigger. No transformer, no coil, no MOSFET,
nothing but simplicity... Think I'll work on that as a winter project
maybe next year or the year after that or so.
