That is true that the tank capacitor is charged to only one voltage at a 
time, but if you are charging it to +10,000 volts, then +10,000 volts, etc, 
does the output on one end stay as +100,000 volts, then +100,000 volts, 
etc? I guess what I meant by my first question was whether or not the 
polarity of the secondary output of a DC coil still changes. (thus making 
it AC) From my limited knowledge of inductance, I'm guessing that the 
output is still AC seeing as the magnetic field from the primary coil still 
forms and collapses (when the primary goes from 0 to +whatever, then back 
to 0 ) which causes a charge to flow back and forth in the secondary, right?

Hi Chris,

It is all the same. When a gap fires the cap is charged to a given
voltage, say +10000V. For that moment in time, the cap voltage looks just
like DC to the coil. If the cap is -10000V the next firing or +10000
again, it really does not matter. You second question is messy ;-)) but see:
