DIAGRAMS
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

 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.
•  Power voltages is dc 14.4V and fed with regulated dc 
power supply from ACC and BATT cords.
•  Voltages and waveforms are dc with respect to ground 
under no-signal (detuned) conditions.
  no mark : TUNER
•  Voltages are taken with a 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.
