Actually it is the amount of magnetizing current that a certain core
size can handle.

Uuh, I think this comment is bound to lead to some confusion.
Removing shunts does NOT increase the output voltage. It will
increase the current capability (and thus VA and ultimately the
output spark length of the TC), but it canīt, wonīt, doesnīt have
to, increase the output VOLTAGE of the sign (or any other) xformer.
