Right, that's the epoxy.

This one has been "adjusted" (ie tampered with.)

I'm hoping to figure out a way to set these back again. I have an idea, but I 
haven't tried it yet. I got one response from someone with a spare 4 pin 
connector body to fit these, but I still need a second one. My idea is to hook 
up a pair of identical PSs with the secondaries bucking one another. With a 
signal applied to the primaries I should be able to adjust them until their 
secondary signals null each other out.

If I hook up a hose with a Tee to each PS, then I should be able to suck on 
them and verify that the null is good over a reasonable range of vacuum.

Seems reasonable, I just won't know if it will actually work until I try it.
