[Johnson] Rear 120VAC Connector on Johnson Transmitter

[Paul]

I use 300 ohm antenna plug connectors. Perfect fit. They came as male/female pairs and we used them back in the dark ages of B/W TV for 300 ohm antenna interconnects. 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.
 
I've seen ones made with old crystals (HC-6 type?) that have the proper pin spacing. Remove the crystal cover and then the crystal inards. Drill hole in side of crystal cover and insert grommet. 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.
