The Saint Jean Baptiste Vintage FET Microphone
A vintage German design. Modeled after the Neumann U47 FET. We wanted to use our own M7 inside the original design of the FET; however the polarization voltage drawn from the shared wimpy 48V phantom proved to be a challenge. We use a custom booster circuit to get around the issue and a current limiter to carefully portion out the current to each section of the design. The Hi-z portion of the circuit including the FET are all done point to point on Ceramic rails while the rest of the circuit is implemented with modern SMD components. It is an "old meets new" hybrid which retains that vintage tone while saving power to add new features and use the original M7 capsule.
Components:
Right now, my go-to is a Cathedral Pipes St Jean Baptiste (FET 47 type) into an API 512C into Apollo. Cathedral Pipes are amazing.
...of having the same components combined as the Notre Dame tube microphone but with greater flexibility . The Abbey and St Jean Baptiste will give that familiar M7 capsule, PF86 tube, and Cinemag transformer sound!"
I used a TLM 102 for quite a while before realizing I wanted something more like a K47 style capsule. Cathedral Pipes offerings are absolutely amazingly priced. I'd look more at the boutique stuff. The St Jean Baptiste from them made me not look to the 102 anymore.
