BTW, I checked, and the molex pins I tried aren't steel or anything
magnetic. They do have sharp edges, so maybe that's why they appear
to be marring the eyelets.
Ah... important to know! I had thought the eyelets to
be steel, but
it sounds like they are plated brass, then.
I had been considering trying molex pins, but apparently that's going
to be a poor choice.
For what it's worth, mini-banana plugs *do* fit nicely. They have two
or three problems, though. First, the housings are fatter than the
simple pins, so you can't use both of the side-by-side eyelets. That
means you'll end up needing the stackable ones. Second, they are
horribly expensive. Third, they aren't very authentic.
Well, sorta. The 911 patchcord kits sold with for the H9xx and K9xx
mounting panels (logic lab gear) consisted of various color coded
lengths of wire with stackable mini-banana jacks on the ends. So
DEC at least used mini-banana patch-cords at one point, on their
higher end stuff.
Thanks for the info, Vince,
You're welcome!
