THIS  NOTE  IS  COMMON  FOR  PRINTED  WIRING  BOARDS  AND  SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each block.)
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.
•      f  : Internal component.
•  2 : Nonfl ammable resistor.
•  5 : Fusible resistor.
•  C : Panel designation.
•  A : B+ Line.
•  B : B– Line.
•  Voltages and waveforms are dc with respect to ground 
under no-signal (detuned) conditions.
  no mark : TUNER (FM) 
 
       
*
      : Impossible to measure 
 
•  Voltages are taken with VOM (Input impedance 10 M
).
  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.
