OK. Now I don't feel like such a goon. I wouldn't have foreseen that despite my ham radio experience with spark gap equipment. Looks like it's time to get a new Spark and a couple bits and pieces from Mouser.

OK, so if my original circuit looked like this:

                1k
GND____/\/\/\______/__5v
                        |
                     Pin 5

Then the new one would look like this?

                1k         D1
GND____/\/\/\____|<_____/__5v
                                   |
                                Pin 5         

No... like this:

                    1k
5v___/____/\/\/\__________P5
             |                   |
             >                  ^  D1
             >  1k             |
             >                  |
           GND              GND
