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.
