It was the polarity of the cap being hooked up in reverse causing the clicking. It was also keeping the voltage from climbing past 72v. I swapped both of them around and now the clicking is gone and I get a steady 2.203 khz on both negative and positive output. The cap also is moving up quickly beyond 300v when I checked. It only puts out a single gnat noise now.

Now we'll see how the radiant night treats it.
