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.
•  Components for right channel have same values as for 
left channel. Reference numbers are coded from
•      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 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.

•  The voltage and waveform of CSP (chip size package) 
cannot be measured, because its lead layout is different 
from that of conventional IC.
For Printed Wiring Boards.
Note:
•  X : Parts extracted from the component side.
•  Y : Parts extracted from the conductor side.
•      f  : Internal component.
