Any one have a wiring diagram for D104 with pre-amp but with no E/R switch? All of the specs I've downloaded show this slide switch. Mine does not have one and I need to check the wiring layout of my old mic. Years ago I did a mod but I cannot now recall what or why. PTT works but no audio to Drake TR4 with new battery.
