Re: Magnifier Primary Capacitors - EQUIDRIVE vs. STANDARD

Dan,

Electrically and performance-wise, two caps in series, no matter if
separated by the TC primary or back to back, act like a single cap with
twice the voltage rating and half the capacitance of a single cap.  But
esthetically, it has some appeal for those who value symmetry and scientific
names to describe their setup.  One could argue two caps might help isolate
the primary from the 60 Hz power source, but the equidrive setup is probably
just as potentially lethal to the careless person who contacts a primary
while the coil is in operation as is a single cap configuration.
