[Elecraft] Pomona Adapter Query

[Scott Walker]

I have the recommended Pomona BNC-to-dual binding post adapter for use with my KX1.  It looks like some kind of wire termination might fit into the ends of the binding posts.  Has anybody got a recommendation for what kind of wire termination would fit snugly into those openings?  Banana plugs are too large.  It would be nice to have a plug-in option, in addition to crimping bare wires.
