[Kenwood] MC-60A

[Garey Barrell]

The MC-60 will operate without batteries from transceivers that provide 
power on Pin 5.  There is a Zener/Emitter follower regulator and an IC 
amplifier.

The preamp in the base of the mic is either in-line or bypassed 
depending upon the On-Off switch on the baseplate.

All described in the MC-60 'manual' sheet.
