I have got discovered vintage AKG CK12 Brass capsule at home.

I would like to build a mic with this capsule and use a standard one-transistor Jfet circuit of ECM electret mics (common source either

Hi there,

I'm trying to understand why a good C12 sounds the way it does. Of course, the main thing is the capsule. From the info I gathered, the contruction was quite complicated and involved many parts and a lot of precision work to get it right. Even if consistency from sample to sample wasn't great, most old CK12 capsules were/are certainly better than AKG's own modern CK12.
