Here is what Jim Williams has to say about it. Even if it would work, good luck finding one
| It is the same capsule used on the 414B-ULS. They were sold in '81/82
| then discontinued. I believe only 4 are in the U.S., I have one of
| them. They won't polarize from a 460B body because the 10 gig bias
| won't charge up the capsule due to internal resistance built into the
| CK-4.
| One very cool mod is to open up the capsule and carefully lift the
| gold pin from the rear capsule. This converts it into a cardioid
| capsule. If you use a C-60 body you create a poor man's C-12A. (At
| least one with a newer capsule). I used to display this capsule at AES
| shows as it always grabbed visual attention, "what the f*ck is THAT!?"
| Consider yourself fortunate to have found one.
