Bill, Terry, all,

It is also interesting that static gaps often stop firing for awhile (when
the total gap spacing is wide) and
then start up again, by themselves.  I would think that if they are firing
at a reduced voltage as they heat, then they would not tend to stop 
firing once they start, yet they do.  Another mystery.
