Ross,

My congratulations! You did a very fine job indeed. Although my 
system is different from yours I have read of your measures and 
observations with great interest.

Unfortunately I faced this flash-over problem between primary and 
secondary coil as well. I will try to wind a primary coil with a 
smaller heigth and without metal screw/parts for the upper wire 
fixture. Maybe it helps.

Using an adjustable vaccum cap parallel to the tank cap for tuning 
is a good idea as well. I tried to find a suitable (some 100 pF/more 
than 20 kVdc) one, but without any success so far.

I am looking forward to visiting your updated VTTC page.

Good luck!

Herwig
