post mortem on the Jalco socket

No obvious problem but for minimal metal and plastic content and makes a
nasty scratchy/clicky noise on turning a jack plug in there, probably
because the tip contact is along the axis of the plug rather than across.

I suspect it was failure to positively disengage the grounding contact as
only something like paper thickness separation with the plug in place. I
could not induce the problem as found and had to take word of owner that he
had to bend the plug one way to make a contact.
