I can't say for certain regarding your 12/30 NST, but my Jefferson 15/60
NST had its core constructed in such a way that the current shunts were an
integral part of the laminations and were not removable.  I failed to
photograph it, but an example of an NST core with removable current shunts
is in my web site on my mini coil page.  This NST was a 4kV/20mA unit.
See: http://www.laushaus-dot-com/tesla/minicoil.htm, 3rd picture down.  The
current shunts are the two groups of short laminations between the primary
and secondary.

Hi all,
 
    I finally got around to removing the metal case from my 12/30 NST so that i
could finish removing the tar.  The tar came off very easy after this, and both
secondaries read about 10 ohms to ground (i guess the tar shorted it out).  My
question is how is this transformer current limited?  I can't seem to figure
out where the shunts are.  It is sitting in a bucket filled with gasoline right
now and will be until next weekend.  If it helps it is a Jefferson Electric
NST.
