Obit's

Ok, sorry about this, but I accidentally deleted the
question about OBIT duty cycle, so I don't exactly
remember the name of the person who asked.

I ran an Obit as the power supply for my disruptive
coil, before I got my 12/60 NST.  With a resonant MMC,
static gap, and a 6" dia secondary it gave at least
24" sparks to a grounded target.  SQRT(220(input)) x
1.7 = 25.21....., so it's not a bad little power
source for a first coil, that's for sure.  In the ones
I've seen, one side of the secondary is connected to
the case, and the other goes to an insulator.  I used
mine for a lot of experiments, and didn't use a filter
in TC use.  That was 7 years ago, and the same
transformer is being used by my friend Dan Williams in
a small disruptive coil.  He used a 3.5" secondary
with a 11.5" winding length and the OBIT gave 15"
sparks.  I think with optimization he could get more.

I am not sure what duty cycle these were designed for
(probably just to kick the furnace on every time
someone's heat was activated), but they have been used
successfully by many coilers.  Hope this helped!
