I don't know if it's the same thing that I experienced at my much lower 
1kVA level, but I was having the same sort of problem (discharges from 
the middle of the secondary) until I raised my secondary up to loosen 
the coupling.  When I did that, the spark-over stopped and I actually 
gained two inches or so of spark length.
