OK, so the capsule I checked, and was convinced had problems made it to the manufacturer, and he told me that he could find no continuity between the backplates. I saw it there. This isn't the first time I've used a DMM to check continuity. So I went and performed the same check on the working mic and saw no continuity, as expected. I know the manufacturer is a stand up guy. He's not out to cheat anyone. Am I losing my fucking mind??!
