Would anyone be willing to help me understand how I might use an RFT m94 capsule with the Royer SDC mod (schematic posted below)?
I've successfully got it working with an oktava mc012 but not sure how to proceed with this capsule.
There is a resistor inside the m94, which I understand is to bring the standard MV body 60v down to 40v.
I can’t find info on whether the backplate or diaphragm for m94 should be polarized, also whether the capsule pin is the backplate or diaphragm. Also not sure if either are attached to body, ehh.. :-\ and how this would affect the circuit.
THANK YOU!
