    Need schematic/wiring diagram for SBE amplified desk microphone.  Sorry, don’t have model number.  It’s black wrinkle finish w/silver PTT and Lock buttons.  Trim around mic element is also silver.  Has gain adjustment.  In process of refurbishing it.

    This microphone is probably some sort of OEM product from Turner, Shure, or another manufacturer. The preamp is usually nothing more than a transistor and a couple resistors and caps, and can be easily drawn up with a little studying of the circuit. Try to find a power microphone that looks almost identical to yours and xref from there.
