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 ?

AKG 451 plus CK-8 Short Shotgun


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.

AKG A-51 swivel (knuckle joint) for C451/CK1 etc...

I'm looking intensly for an AKG A51 swivel joint to mount CK1 on C451 bodies angled from the axis...

Seems to be difficult to get these days (I don't know why so many companies discontinue their cool stuff!)

If you happen to have one in good working order and would like to sell it, please contact me...

best regards

AKG C451E and C460B with different capsules (CK1, CK1S, CK3, CK 61, CK22, CK62)

Hello, I'm new here and I don't know how much interest for this kind of stuff is there, but anyway: I did some comparisons between different combinations of AKG bodies and capsules; the file names are more or less self explaining.

460JW is Jim Williams moded 460B body, 460Stock is the stock body, and which capsule is attached you cen derive from the file name.
