Ive got a shotgun mic that started acting up, sounds like a loose wire. I managed to get it apart before busting something. The short tube with XLR connector has the gnd rivited to the centre of a tube inside that one that then goes up into the long tube that houses the electronics and inserts. The other 2 xlr pins run wires up the outside of this inner tube to the long tube and onto the circuit board. I found thatvthe gnd wire is open circuit between xlr pin and rivet on top of short tube. How would that come adrift? I cant get short tube undone. Any special way? Anyonehad same problem?

Thanks

It is almost impossible to suggest anything as we have no idea what mic you are talking about, nor do we even have a photo to look at.
We don't know how the XLR pin assembly is secured into the microphone. Some XLR pin assemblies are secured with a screw which goes into a lug where you could "get" the shell/ground connection. But an actual wire is always better, which is likely why they designed it that way.

Anything you can do to give us a better idea of what you are asking about would be very helpful.
Microphone brand? Model number? Photos of the problem?

Sorry, im not usually that vague, ill post pics tomorrow. Its a cheap mic, around 50 bucksbi think but im curious as to whats in the section that has failed.
