[TCML] I should have taken more electrical classes/MOSFET TC

[Scott Bogard <sdbogard@xxxxxxxxx>]

Greetings all,
     All right, I been doing a bit of reading and I need something
cleared up in plain English.  A MOSFET is just like a vacuum tube
triode, (minus the obvious things like a plate transformer and a
vacuum) except a triode turns off with voltage, and a MOSFET turns on
with voltage, is this correct?  A BJT turns on with current, and
voltage has little to do with it, what turns on an IGBT?  Anyway
concerning the MOSFETs and tubes, if the above assumption is correct,
why are there not designs for MOSFET based coils that are similar to
the Armstrong oscillator tube coils (for those who are looking for
little arcs at very little cost (MOSFETs are cheap, tubes are pricey
and require external circuitry.))  If I am understanding this
correctly it should be relatively easy to design such a circuit as you
should essentially just reverse the direction of the windings, and
maybe hook it to the positive rail instead of the ground?  (Well
relatively simple for those who have actually used MOSFETs without
exploding them or burning them, MOSFETs and me do not get along, I
don't know why, I never did anything to them (except blow them up, but
that wasn't my fault was it?))  Anyway just looking for answers,
perhaps I am totally misunderstanding how to use them properly, and an
electronics course might have helped with that.  Thanks for your
patience!

Scott Bogard.
