Note: The components identifi ed by mark 
0 or dotted line 
with mark 
0 are critical for safety. 
 
Replace only with part number specifi ed.
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 speci-
fi ed.
•      f 
: internal component.
• 
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.)
For Printed Wiring Boards.
Note:
• 
X : Parts extracted from the component side.
• 
Y : Parts extracted from the conductor side.
•      f 
: Internal component.
•

*  Replacement of IC102 and IC103 on the MB1306 board used 
in this unit requires a special tool.
Note: When the AMP board is replaced, spread the compound 
referring to “NOTE OF REPLACING THE IC3102 AND 
IC3302 ON THE AMP BOARD AND THE COMPLETE 
AMP BOARD” on servicing notes (page 5).

B : B– Line.
•  Voltages and waveforms are dc with respect to ground under 
no-signal conditions.

*
  : Impossible to measure
•  Voltages are taken with VOM (Input impedance 10 M
Ω).
  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.

•  The voltage and waveform of CSP (chip size package) cannot 
be measured, because its lead layout is different from that of 
conventional IC.
Note: When the AMP board is replaced, spread the compound 
referring to “NOTE OF REPLACING THE IC3102 AND 
IC3302 ON THE AMP BOARD AND THE COMPLETE 
AMP BOARD” on servicing notes (page 5).
