Phantom-powered dynamic mic preamp based on the FetHead. A very similar circuit is also used in the Cloudlifter.
STL files for a 3D printable enclosed are included in the attached zip file, as well as a template PDF for shielding, which can be printed and glued to aluminum foil and cut out. Be sure to 3D print both the body and the lid.
FetHead is not a registered trademark, therefor I should be permitted to use it in the title.
