Hello,
In my attempt at reproducing a Boonton 2500, I've discovered that
the power sensor connectors are impossible for me to find anywhere.
They're connectors like the white ones here:

They're also used on the backs of the power sensors:

The male end looks like this:

And they mate like this:

I've measured the one connector I have and have produced a 3D
sketch:

And the face view:

Can anyone find females + males of these? More precisely, I'd like
a panel-mount female (receptacle) and a couple in-line (attached to
cable) male plugs. A pre-assembled jumper with male ends would work
too. It would also be awesome to find an adapter from this weird
standard into something more readily available.
Any suggestions?
