Well, let's see. I bought the mic from Musician's Friend. I got the Lundahl transformer from K&K audio, but later went with an AMI transformer from Tab Funkenwerk. The circuit was based on the U47 using a 6205 sub mini tube instead of a VF14. The capsule and mount are available from Siegfried Thiersch, who skinned capsules for Neumann back in the day. They are expensive, but sound amazing.

You could also use a Peluso Capsule. I have a source for less expensive K47 capsules as well. Not as good as the Thiersch M7, but about as good as a Peluso.
