Opening a Berhringer 8000 mic

Guess I am screwed. I have a mic from my Anthem AVR, but it rolls off @ 6K and their cal file is encrypted. So, DSP, or Dayton USB, or another Behringer if I can't limp by "good enough". I gave away my old Panasonic capsule I made, gasp, 30 years ago! Hate to spend money for a couple of last projects.
 
Guess I did not pull hard enough as the board came out this time with some wiggling. I hate to apply force before I now how they are supposed to work. Did not see any fault; but put it back in and it seems OK. Maybe I can limp through.

Yea, uncalibrated are cheap. Does me no good though as I don't have a capsule calibrator and they cost more than a mic.
