I just aquired a Neuman U87, after inspecting it I found the rear capsule to be in much worse condition than the front. Has anyone ever tried flipping the capsule around? By this I mean actually disconnecting the leads from the capsule, flipping the capsule around and reconnecting the leads to the side now facing them. I was'nt sure if the capsule was polarized in some way that connecting it backwards would have negative effects.
