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

Forums

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 ?

AKG 451 plus CK-8 Short Shotgun

Forums

I read something today in the old products section of the AKG website on the old CK-8 capsule for the 451 preamp. I knew I had one of these inside a zepplin windshield in the store, but hadn't done anything much with it since I had other shotguns. What made me think was that AKG noted it's use on hand held vocals, where it was good at reducing popping.
