Two of these in series would be nice   :)   I know that some people
use 6kV for their coils, but lower than that makes it harder to build
a suitable spark gap.  You could over-volt the input by 20% or so,
to get amost 5kV, then use resonant charging to get another 15% 
voltage rise or so, and use a sync gap at 120 BPS, and it would
probably work fine.  You'd need a large cap value for any kind of 
decent power handling though at the low voltage/low BPS.

Or one of them could power a nice tube coil.  Is that 5.5 amps on
the secondary?  That's a lot of power, I've never seen a potential
transformer rated at 22 kilowatts.
