Ed,
	I've not enough experience to make more than a general
suggestion. Try 2 then 1;) 

	Did you make any other changes to your primary circuit besides
shortening the interconnection length and changing it Cu tubing.
Change the number of gaps connected in your static gap? Regap your
rotary gap? 

	I just looked at your old photos. Did you change the length of
wire from your filter board to the TC? I'm poking around looking for
some change in the ballast to pig to primary cap and spark gap that
has changed the ~60Hz resonance.

	Have you remeasured your primary cap to see if it has changed
value?

	Just thinking out loud.
