	Don't pitch it; just cut the wire in the damaged region, remove the
turns you don't like, rejoin the ends (avoiding any sharp points) and
you should be back in business.  I've done this where a part of the coil
got burned due to careless (usually arcing inside the form) and found
the coil was repaired and usable.  In the case of the burned form I find
that clearing away all of the blackened material and then varnishing or
shellacking (sp??) the cleaned up form seemed to work just fine.  Of
course, all my coils run off NST's and I'm not sure I'd want to do that
with a bigger device.
