I got a Brauner Phantom V really cheap and would like to get it functioning properly. It works but sounds terrible except for the rear diaphragm while in figure 8 mode. That sounds pretty awesome. I tried reversing the capsule but with the same results. The inside of the mic body has burn marks but the circuitboard looks fresh, leading me to think it's been rebuilt. I suspect it's the polarization voltage and ordered some J201 FETs to try that but a schematic would be really useful.
