Has this happened to anyone? Is it possible to fix or should I send this in?
-
superglue? its not a critical component, if you get it back in place by any means necessary it will do what it needs to do

You shouldn't have to send the microphone in. You may be able to make a repair yourself, or get a new replacement grid from DPA which will slip on in its place.
First, first pull the remaining little black plastic "cuff" off of the microphone body - the black-band part of the interference tube assembly which connects the tube to the microphone. It may be tight, but it's a slip fit just like a 406x grid. You'll need to remove that from the microphone either way. After removal a new grid can be slipped on directly. Or..
Next I'd examine the removed cuff to see if there is a little groove into which the tube fits, and carefully play around with reassembling the two back together with the intent of super gluing them. If it's easy enough to get the tube into the groove, it will probably be advantageous to apply a minimal amount of glue to the end of the tube first, then re-assemble the two parts. That should minimize the amount of glue applied and get it all in the appropriate spot. If you have to apply glue after assembly you are far more likely to get excess glue which may clogg portions of the grid or prevent a good fit with the microphone body.
Let the glue cure fully and inspect the inside closely for any any glue runs, blobs or whiskers which would interfere with the slip fit, prior to replacing the tube on the microphone. Don't try to superglue the grid to the cuff while the cuff is on the microphone, else you are likely to permanently superglue the cuff onto the microphone inadvertently.

Regarding super glue..... I have seen it posted on other sites that it super glue is not recommended for use near microphone capsules as some of the volatile compounds can react with the capsule membranes. No idea if this is the case for DPA, but I would check with them before attempting a glue job.

Another good reason not to glue it back together while it is attached to the microphone! Remove the cuff part from the microphone first. The volatiles evaporate upon cure. If in doubt, reassemble to the mic the following day.
