Nice work but don't run it for too long without a ballast resistor or you will burn up the coil (unless it has a built in ballast which I believe 79-> don't). With no ballast, the primary current is around 2X which means power dissipation is around 4X. The ballast spec is 0.85 to 0.95 ohms. It should be easy to find a replacement.
I am currently using an aftermarket coil (1.5ohm). Will stop by at parts store later today and find a ballast resistor to replace, hopefully mine is just bad and not the full cause of the issue.
