It is the transformerless circuit used on several neumann microphones. I wonder if someone have a schematic of it. I wonder if it is similar to the Geffell MT71s https://recordinghacks.com/images/mic_extras/gefell/MT71S-schematic.gif
My interest is in the KU100 head microphone. it should use the Fet100 circuit.
