Subject: 19 kV MOT stack?

Hey everybody.
     I read in the archives that somebody tried to parallel a MOT and NST to 
get high voltage and current, but I have a slightly different idea.  What if 
you took a center tapped MOT or OBIT, to get your volts up, and put the 
outputs to the case of a MOT, to get oober current.  The first thing to come 
to mind is shorting the MOT, but MOT stacks have been successfully extended 
to 8 MOTS, 6 more reliably, and by doing something like this, you could put 
the primary at a higher potential, reducing the chance of an arc over.

So If you have a 15 kV NST, each side is 7.5 kV and the MOT primary sits at 
2 kV, so the MOT primary is seeing 5.5 kV difference, just over what a 6 
stack would see, and less than an 8 stack.  So you could get 19 kV with 6 
MOTs and an NST, and you could float the  MOT cores from the secondary to 
reduce stress further.  My biggest question is would excess current draw 
from kill the NST or doesn't it work that way (would the current come from 
the MOT, or does it have to be pulled from the ground in the center of the 
NST or OBIT)?  Just a thought.
