Variac blowing fuses (another newbie question)

Got a lot of great advice on this from you guys.  Just wanted to let 
you know how it turnied out.
I added PFC/motor run caps only - & didn't do anything to lower tank 
capacitance at this point (that was Plan B).  PFC seeed to take care 
of it.  I've run the coil a good number of times for 30-45 second 
durations, even with a lot of continuous arcs to ground - and even 
though I only had a 15A replacement fuse in stead of the original 
20A.  I had no further blown fuses.
PFC alone may not be the ideal solution.  And I may ultimately be 
better off lowering my .03uF tank capacitance as suggested by a 
number of you (I have a 15/60 NST).  But at least I'm back in the 
ozone business for now.
As a side note, when my motor run caps arrived from Mouser, they 
looked identical to the picture of capacitors "not suitable for PFC 
use" shown on Gary Lau's website.  I thought oh @#%, I got the wrong 
ones.  But I checked again, they are shown as motor run caps on the 
Mouser shipping order.  And Gary's picture shows the brand name 
Phillips, while the ones I goe are DCE.  But they look identical in 
every other way.  Anyway, I tried them & they seem to work OK.
Thanks everyone.  Dennis Hopkinton, MA

Now to go to work on those bleeder resistors...
