Wiring Revision - Model M - April 24 1950

 Effective with serial 8411 on Spinet Model M Organs,
 condenser C46 has been changed to an adjustable type having a
 capacity of .000024 - .000090 mfd. It is now located inside
 the expression control unit.

 This condenser is used as a factory volume adjustment and its
 setting should not be changed after leaving the factory.

 Resistor R33 and condenser C42 have been removed from the
 expression control unit and are now found inside the amplifier
 chassis, with a small change in wiring which has no effect on
 the operation of the amplifier.
