OK, that means I need to undo the 12 supply and put something higher like the 19 to 20V laptop supplies.

I have a bunch of the 12V is why I wanted to use them.

So, now with switcher DC in = 15.2V from another wall wart, I get
a(56,10,18) --> pulses of 3000V peak.  More like it.
It's not even linear.  12V must be still having some of the
low volt side diode losses figuring in, and maybe...  I'm not sure why.
15.2/12/2 = 1.25   3000/1750 = 1.71  Not the same ratio --> not linear.

I don't have more of this voltage wall wart for other testers, but I'll
make the micropulser board with an on-board
5V to 15+ volt converter soon, and send that instead of wall warts and g30_pulser boards.
