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.
