5-1. NOTE FOR PRINTED WIRING BOARDS AND
SCHEMATIC DIAGRAMS
Note on Printed Wiring Board:
• X : parts extracted from the component side.
• Y : parts extracted from the conductor side.
• b : Pattern from the side which enables seeing.
(The other layers' patterns are not indicated.)
Note on Schematic Diagram:
• All capacitors are in µF unless otherwise noted. pF: µµF
50 WV or less are not indicated except for electrolytics
and tantalums.
• All resistors are in Ω and
1
/ W or less unless otherwise

specified.
• C : panel designation.
• U : B+ Line.
• Power voltage 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.

• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal produc-
tion tolerances.
• Circled numbers refer to waveforms.
• Signal path.
