AKG genuine CK12 Brass capsule: building DIY mic with a single Jfet-transistor

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
source follower)...

Has anyone ever tried to wire such a large capsule with a single Jfet transistor ? Do you think this might work as a decent condenser mic ?

Thank you for the comments!

AKG CK12

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.
Does anyone manufacture a good CK12 type capsule
these days?
