John,

Thank you for the image. Is that your creation? I placed it on a wiki 
page I just started for my EC-1 with a credit to you for the connector 
image.

The 'Original' and 'Ant Conn' look pretty much what I would expect to fit.

Wayne WB4OGM,

If you could find either of those first two connectors at the surplus 
store closing that would be great! The mini banana plugs like the Pomona 
2945 wouldn't be my first choice as they're not a structural pair. I 
guess there are Crystals that can be disassembled that have a similar 
form factor too. I'm not totally clear on that and don't have an image.
