Cleaned Up MOT Stack

Dear List,
I got rid of the "bird nest" wiring on my new 4-pack
MOT stack. The thing cleaned up pretty good!

It doesn't work better, but it sure looks better (and
safer). The spade terminals allow for quick disconnect
of the two boxes should I ever care to go mobile or
perhaps rewire for 120v operation. I used a standard
2-row barrier strip terminal bloc that I found in my
junk box (of course). All spade terminals are both
crimped and soldered. Note the improved adjustable
safety gaps instead of the junky pieces of bent wire.
The pennies are to prevent the safety gaps from plasma
arcing a hole thru the ammo can.
As an interesting aside, I tried all 10 ballast caps
in a single series row on one HV leg between the rear
(grounded) and front (floating) MOT boxes. Performance
was abysmal. I broke them up again into two rows of 5,
one row on each HV leg, and performance was good
again. I wonder what that's about? Why on earth would
it matter how I series my ballast caps? Oh well--just
one of those things.
Most of the time I run with 8 series MOT caps for
3300VA (predicted, not measured). The light-duty 15A
orange power cord (plugged into a 240v/20A outlet)
barely gets warm. Life is good.
