Doug, could you tell a little more about your power source and sparkgap, please.

Gary, That is my plan but first I want to be getting the most I can out of
the coil.

Assuming that you still have those sliding secondary coils to facilitate
coupling adjustment, can you slide them while the coil is running and see
if spark length strictly diminishes with lower coupling, or if there are
any peaks or nulls along the way?

Here is another video of the adjustable coupling. original primary was 10
turns .060 wire, this primary is 4 turns of 1/4" copper. Both primary's

are

5" total diameter. Performance is much better!
