["garry neeley" <bamacoiler@xxxxxxxxx>]

I finally found the problem.  I missed the ground on one of the filament
pins.  Thanks to everyone for all there help, and a  special thanks to Dr.
Spark for pointing out the issue. 1st light I was able to obtain about 12
inch discharges so I'm off to tune the coil.  Thanks again for all the help.
