•

X

: parts extracted from the component side.

•

Y

: parts extracted from the conductor side.

•

  W

: indicates side identified with part number.

•        

f

: internal component.

•

specified.

•         

f

: internal component.

•

C

: panel designation.

•

A

: B+ Line.

•

B

: B– Line.

• Voltages and waveforms are dc with respect to ground

under no-signal conditions.
no mark: SACD PLAY
(          ) : CD PLAY

• Voltages are taken with a VOM (Input impedance 10 M

Ω

).

Voltage variations may be noted due to normal production
tolerances.

• Waveforms are taken with a oscilloscope.

Voltage variations may be noted due to normal production
tolerances.

• Circled numbers refer to waveforms.

• Signal path.

J

: CD

c

: CD DIGITAL OUT (OPTICAL)

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

Note: The components identified by mark 

0

 or dotted

line with mark 

0

 are critical for safety.

Replace only with part number specified.
