i have a Beyer M201 mic on which the diaphram has become unglued from the rim on the capsule body. This results in it having no tension to hold the diaphram clear of the body. Does anyone have any tips on how to re-glue it and tension it back up. I've had a go, trying to pull the diaphram out with sticky tape whilst the glue dries, but it didn't really work. Is this a lost cause?
