Thanks - yep that was me.

Nothing wrong with 22, 900 volts, as long as your caps can handle it and you 
have a gap that can break and quench it.

The trend is for larger systems to use higher voltages.  Just be forewarned that 
quenching is tougher.  Your transformer will be very good for magnifier work, 
which does work well at higher input voltages.

You can run a 10 kva pig up to 30 kva in Tesla duty.  Be aware that *some* 
pigs will saturate and wimp out before this power level.  I'd bet money yours will 
do at least 20 kva.
