I have a "bullet" microphone used for blues harmonica. It was modified by a technician in a now-distant city about 10 years ago. There is a very small set-screw thread that has been stripped. It did hold a wiring connector in place.
I'd like to find someone in my area who can drill out and re-tap this for a new set screw. Perhaps even add a second set screw on the wiring connector. My zip code is 20770. I am in Greenbelt, MD, near the District of Columbia. Please contact me at harmonicablu@yahoo.com.

Thank you,
Blu
