Microphone Schematic Archive

There are many places on the internet where one can find scans of the original schematics of historic microphones still popular in today's recording studios. We decided to create a slightly different resource. Our layouts have been created such that the input connector, transformer, tube and ground line are in the same position for each schematic. The goal is to create an educational resource library where comparing and contrasting the schematics of different tube microphones becomes easier due to the similar placement of the major components of the microphone.
