Recently pickup this microphone. I’ve fixed several wiring/solder issues, pinched wires, wire strands on circuit board, cleaned the relays, stopped them from squeaking and I believe the 5k potentiometer is bad. The mic element is in fine shape and working great as tested on my other D104 mics.
Used a Jonard OB-1/3 burnisher tool on the contacts along with Deoxit D5.
Here’s the parts list. Planned on only replacing the capacitors unless forum wisdom says otherwise.
