yeah, Obi Van Quick :-D is the _experimenter_, who thought, that
maximum theoretical efficiency  of the classical coil is 50%, but the
magnifier`s one is 100% :-)
"armchair methods" - d`you remember like Richard Hull (without doubt a
great _experimenter_) told, that the voltage on the toroid didn`t
depend from its capacitance at all? but you have objected, that
_theoretically_ it can`t exceed a definite value, in accordance with
the energy conservation law? do you remember what did he reply to you?
i can remind you :-)))

NO! i must know this BEFORE, else - what`s the use of this list? ;-)

step function is the very small part of the energy transfer period from
the mains to the cap, isn`t it so? anyway - isn`t it possible to solve
this problem? as i`ve cope with  the power arcing problem :-)

one mot secondary resistance is 113 ohm, i`ll have 4 of them +
the inductor resistance - not  more than ~700 ohm total. cap`s
impedance - about 32 kohm, the inductor`s one - about 12.5  kohm, so
everything will be cool :-)

me too by the way - even with more greater interest ;-D it`s a pity i
have to wait very long.
