Thank you sir!  Much better, mucho multiple 5-6" sparks (need to increase
topload). New problem though, the secondary is coated with 4 coats of PU,
but I'm getting tons of little sparks comming out of the top and bottom
turns. :(   I'm thinking I did something stupid, I wrapped black PVC
elec. tape around the secondary above and under the windings (just liked
the way it looked), now, am I getting these sparks from the 'sharp'
edge of the tape???  Would a few more coats of PU help smooth it out?

Well, I'll be very happy if I can get 10-12"

Well, you were right about that. :)
