DIAGRAMS
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.
• 
 : Pattern from the side which enables seeing.
•  Indication of transistor.
 
C
These are omitted.

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.
•  A : B+ Line.
•  B : B– Line.
•  H : Adjustment for repair.
•  Power voltage is dc 14.4 V and fed with regulated dc 
power supply from +12 V and REM terminals.
•  Voltages are dc with respect to ground under no-signal  
conditions.
•  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.
•  Signal path.

Note: 
The components identi-
fi
 ed by mark 0 or dotted 
line with mark 0 are criti-
cal for safety. 
Replace only with part 
number specifi ed.
Note: 
Les composants identifi és 
par une marque 0 sont 
critiques pour la sécurité. 
Ne les remplacer que par 
une pièce portant le nu-
méro spécifi é.
•  Note for Replacement of the Transistors
The transistors Q110, 111, 210, 211, 310, 311, 410 and 411 have 
two different ranks: P rank and Y rank.
The rank of these transistors need to be selected properly accord-
ing to each channel. When replacing any one of these transistors, 
check its rank and replace with the appropriate transistor of the 
same rank.
