[NJARC] Microphone question

Sun Apr 17 17:38:50 EDT 2016

A visitor at our museum today (J. Chris Hausler of the Morse Telegraph Club...  jchausler at earthlink.net  ..)) needs to know how to set up and use a Western Electric 600A double button carbon mike. Anyone have info and a circuit?
 Thanks,
Jules
