I am really new to this, but I think I have some suggestions.

where : is the spark gap, and [%] is the capacitor. "\" primary.

630v ?!? 10kV output toa 630V cap? Could be wrong, but wouldn't an
impulse like that blow a cap? Probably need to go with about a 20kV
capacitor. It should stay cooler if problems arise.

My best guess is that these are the problems. Especially the capacitor
voltage rating.
Thanks for hearing me out ;-)
