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 Ωand 1/4W or less unless otherwise
specified.
•¢: internal component.
•2: nonflammable resistor.
•5: fusible resistor.
•C: panel designation.
Note on PrintedWiring Boards:
•Y: parts extracted from the component side.
•¢: internal component.
•b: Pattern from the side which enables seeing.
•Indication of diode
•U: B+ Line.
•V: B– Line.
• Voltages are dc with respect to ground under no-signal
conditions.
no mark : TUNER
• Voltages aretakenwith aVOM(Input impedance 10MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Signal path.
F: TUNER
E: PB (TAPE1/DAT)
a: REC
d: PB (TAPE2/MD)
J: CD
I: PHONO
Note: The components identified by mark !or dotted line
with mark !are critical for safety.
Replace only with part number specified.
