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 1/4 W or less unless otherwise
specified.
•f: internal component.
•C: panel designation.
•U: B+ Line.
•H: adjustment for repair.
• P ower voltage is dc 14.4V and fed with regulated dc pow er
supply from ACC and BATT cords.
• V oltages are taken with a V OM (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.
F: FM
f: MW/LW
L: BUS AUDIO IN
E: TAPE PLAY
• Please refer to servicing notes (page 2) for system of
TYPE A, B and C.
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.)
Caution:
Pattern face side: Parts on the pattern face side seen from
(Conductor Side) the pattern face are indicated.
Parts face side: Parts on the par ts face side seen from
(Component Side) the parts face are indicated.
