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.
• 
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 (detuned) conditions.
  no mark : POWER ON
•  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.
 
F : 
AUDIO
For Printed Wiring Boards.
Note:
• 
X : Parts extracted from the component side.
• 
Y : Parts extracted from the conductor side.
•      f  : Internal component.
• 
 : Pattern from the side which enables seeing.
  (The other layers’ patterns are not indicated.)
Caution:
Pattern face side: 
(SIDE B)
Parts face side:
(SIDE A)
Parts on the pattern face side seen 
from the pattern face are indicated.
Parts on the parts face side seen from 
the parts face are indicated.
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.
Caution:
