A ball gap voltmeter, but they might not work well at all under AC 
conditions.  Probably need a high voltage stack probe with a shielded 
body.  The voltage is not terribly high in this case.  Ross sells them, or 
you could make one for vastly less money.  I think the copper rod would be 
ok with a little loading from such a probe.

The camera (me) did not take that good of picture.  Best to set it up 
yourself so you can see it first hand.  I did not see anything out of the 
ordinary.

Cheers,
