Hi again,

Yes! It works! (kind of) We were able to get it running for a while. All 
that was needed to stop those racing sparks was to raise the secondary a 
half an inch or so. By the way, thanks to everyone who suggested it. We 
were getting about 20" sparks when after about a half hour of playing 
around with it (it wasn't running the entire time) we noticed a spark on 
the bottom of the mmc. Not wanting to kill our new capacitors we took it in 
for the night. It wasn't untill this morning that I noticed that one of the 
bleeder resistors had been completly carbonized! There were scorch marks 
underneath it also, but I didn't pay much attention to it thinking that the 
resistor may have just blown by itself. So I just put a couple of strips of 
electircal tape over the mark, and soldiered a new resistor on. However, 
when we blew our second resistor this night, it became apparent that the 
resistor is probably arcing to the cap on the other side of the perfboard. 
So is there anyway to stop ! this? Sigh - fix one problem and another one 
pops up...
