The "great way to damage an NST" design sounds like the way my "dead man's
coil"  is configured!  Here's schematic of what I'm currently running...

                          RF choke                      gap
----- || -------0000--------+------> <------ out to primary top

Sounds like I should swap the gap for the cap.  Do I understand correctly?
