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.
•  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 voltage is dc 14.4V and fed with regulated dcpow-
er supply from ACC and BATT cords.
•  Voltages and waveforms are dc with respect to ground 
under no-signal (detuned) conditions.

•  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.

For Printed Wiring Boards.
Note:
•  X : Parts extracted from the component side.
•  Y : parts extracted from the conductor side.
•   W  : Indicates side identifi ed with part number.
•      f  : internal component.
• 
 : Pattern from the side which enables seeing.
  (The other layers' patterns are not 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.

•  SERVO board is multi-layer printed board.
  However, the patterns of intermediate-layer have not been 
included in this diagrams.
