Malcom,

I don't think it is heat related.  I have never noticed the capacitor
terminals getting hot - warm maybe.  It isn't something that works ok
sometimes and then quits.  Right now, it is in the failed mode all the time.
 Maybe I will set up a bench test using one or two neon transformers, the
small variacs, the normal high voltage filter board, static gap and a length
of 12 guage wire to simulate the primary.
