THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each block.)
For Printed Wiring Boards.
Note:
• X : Parts extracted from the component side.
• Y : Parts extracted from the conductor side.
•
f
: Internal component.
• : Pattern from the side which enables seeing.
(The other layers’ patterns are not indicated.)
• Waveforms

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  and
1
/4 W or less unless otherwise
specifi ed.
•
f
: internal component.
• C : panel designation.
• 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 (FM)
• Voltages are taken with a 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.
F : AUDIO
f : TUNER
d : USB
E : AUX
