BULLETIN # 953
MODEL: MC-55
SUBJECT: Change in Mic Element (T91-0328-08)

The new Mic element for the MC-55 comes in two pieces.  One piece is a
two pin ECM and the other piece is a spacer.  The spacer is required as 
the new ECM is half the size of the old one.  The wiring configuration
is somewhat changed for the installation of the new Mic element.  The 
figures below show the original configuration, the new configuration, 
and the assembly.  The black wire is not used with the new ECM and a 330 
ohm resistor is installed on the foil side of the microphone amplifier 
board.  The leads of the resistor should be insulated with electricians 
tape or shrink tubing.
