The electronics involved really aren't a mystery, or particuarly difficult, especially given that AKG has published the schematics. This is a problem of machine work, not electronic design. I don't do hardly any machine work, and I'm mainly only interested in my own microphones.
Dear Jon,
I think the simpest design would be as follows:
- small battery box, includes standard capacitors, but also polarization circuit to get 60V.
- the cable would be two wires, one for each capsule, joined in a 4pin miniXLRf, mates with a 4pin miniXLRM at your battery box. Each cable is: ground, audio, and +polarize. 4pin miniXLR is: ground, L, R, +polarize.
- hard wire (solder and epoxy behind) to a pair of CK6x capsules. Each capsule would have the FET from a Church, AT853, or similar capsule. Hardwire/solder to capsule, then put brass mesh shield, finish with epoxy backing.
I think that is a minimal setup. If it worked, perhaps the mech. people would be inspired to build something that would screw to the capsules.
