Initial eyeball guess was an improvement only in the 5 to 10% range,
a hotter spark. It's hard to make accurate measurements when you're
jumping up and down with excitement ;)

Secondary voltage will jump two feet to ground, melting anything
in its path - actually quite a lot of voltage for a magnifier driver.
I expected a lot of corona. Driver is 9.17 mh, resonator is 18 mh.
