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.

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.

  : 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.

Replace only with part number specifi ed.
Note: When the complete MAIN board is replaced, the 
destination setting is necessary. Refer to “NOTE OF 
REPLACING THE COMPLETE MAIN BOARD OR
