No they would not, because the AKG bodies have a FET in them already, what you see when you unscrew the cap is the connection between the FET and the capsule.
You need a bare polarization voltage to transmit over a long enough distance to the FET at the capsule, there is no way to get that polarization voltage from the connector on the bodies. This is what i've gathered from my ideas and experiments.
I don't know about that. The ck_x caps have a FET in them if I remember correctly & they operate over the mk46. Seems like the ck6_ could be operated in a similar fashion if a FET and ? was added in the collette.
Exactly. You need to add *at least* one FET in the collette. I've added two, one to acts an buffer/amplifier and one to act as a constant current source for the amp. So, in the collette I will put: two FETs, two 1Gohm resistors and a few other parts. For now I'm going to just seal it with copper foil/tape and see if that works.
I'll post results when I do this. But in the meantime, if the person with the Collettes wants to get back to me, that would be much appreciated.
