Paul,
I dug around the old TV junk box and found two female ends and one
complete connector.

It is the exact same item (male portion) that came with my original factory Johnsons. Believe it or not Radio Shack (when they were a real Radio Shack, ie you could buy real components) carried them and that is where I got mine. They now appear to be close to unobtanium, and the ones I have are probably close to 45-50 years old. No, sorry, I have none to spare. They are clear (at least almost clear after all this time) plastic with holes and screws at one end and proper spaced pins at the other. Insert stripped wire into the holes at the end and fasten with the screws.

Insert wire thru grommet and solder to crystal pins. Reattach crystal cover with strong glue (like epoxy). Seems to work pretty good if the crystal pins are the correct spacing/diameter.
