Kevin,

This sounds like the infamous xfrmer being sold by Herbach and
Radman Co.  Quite a few folks on this list have bought two of them
and center-tapped the series connection between the two.  They
then beefed up the output connection to prevent arc-overs, and 
ran them in reso-charging mode with around 0.08uF caps.  The 
ferroresonant winding and caps should not be used.  Most coilers
get 4 to 5 foot sparks.  One coiler has obtained 90" sparks I believe
from these transformers.

I prefer to use a pig or potential transformer if you can get one.

Cheers,
John Freau
