I would like to try a mod on my Maudio Nova. It is the second version, with just one small pcb. So instead of going U87 way, why not to try a KM84 circuit? The fet will be 2N3819, maybe different capsule and a T8-T13 transformer.
I took the schematic of the GT55 mic form this very good thread, revised the variations of the circuit (prety much the same without pad or low cut), and did first schematic of the mod.
I did not included R5 and C6 from the original KM84 schematic, are they really needed there? Same with R11, R12 and R13?
Edit: Km84 mod not worth with the original capsule, but with a Neumann K103 or similar becomes stellar.
