• Circuit Boards Location

Note on Printed Wiring Boards:

•X: parts extracted from the component side.

•a : Through hole.

•Y: parts extracted from the conductor side.

•b: Pattern from the side which enables seeing.

Caution:
Pattern face side:	Parts on the pattern face side seen from
(Conductor B)	the pattern face are indicated.
Parts face side:	Parts on the parts face side seen from
(Component A)	the parts face are indicated.

(The other layers' patterns are not indicated.)

• Indication of transistor.

• Abbreviation

AUS	: Australian model
HK	: Hong Kong model
KR	: Korean model

Note on Schematic Diagram:

•All capacitors are in ∝F unless otherwise noted. pF: ∝∝F 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.

•5: fusible resistor.

•C: panel designation.

•A: B+ Line.

•B: B– Line.

Note: The components identified by mark 0or dotted line with mark 0are critical for safety.

Replace only with part number specified.

•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.

F : FM

J : CD (ANALOG)

c : CD (DIGITAL)

p : PB (MD)

l : REC (MD)

I : DIGITAL IN (OPTICAL)

E : PB (TAPE)

G : REC (TAPE)
