*  Replacement of IC102 and IC103 on the MB-1408 board used 
in this unit requires a special tool.
Note 1: When the complete AMP board is replaced, refer to 
 
“NOTE OF REPLACING THE IC6001 AND IC6004 ON 
THE AMP BOARD AND THE COMPLETE AMP BOARD” 
on page 4.
Note 2: When the CN707 on the MB-1408 board is replaced, 
spread the bond referring to “BOND FIXATION OF 
ELECTRIC PARTS” on page 4.
Note 3: When the C6104, C6108 and C6109 on the AMP board are 
replaced, spread the bond referring to “BOND FIXATION 
OF ELECTRIC PARTS” on page 4.
For Schematic Diagrams.
Note:
•  All capacitors are in μF unless otherwise noted. (p: pF) 50 
WV or less are not indicated except for electrolytics and 
tantalums.
•  All resistors are in Ω and 1/4 W or less unless otherwise 
specifi ed.
•      f  : Internal component.
•  2 : Nonfl ammable resistor.
•  5 : Fusible resistor.
•  C : Panel designation.
THIS  NOTE  IS  COMMON  FOR  PRINTED  WIRING  BOARDS  AND  SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each block.)
•  A : B+ Line.
•  Voltages and waveforms are dc with respect to ground 
under no-signal conditions.
  no mark : POWER ON
       
*

•  Voltages are taken with VOM (Input impedance 10 M
).
  Voltage variations may be noted due to normal production 
tolerances.
•  Waveforms are taken with a oscilloscope.
  Voltage variations may be noted due to normal production 
tolerances.
•  Circled numbers refer to waveforms.
