Note:
• All capacitors are in μF unless otherwise noted. (p: pF)
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
specifi ed.

: Internal component.
• 2 : Nonfl ammable resistor.
• 5 : Fusible resistor.
• C : Panel designation.
Note:
The components identi-
fi ed by mark 0 or dotted
line with mark 0 are criti-
cal for safety.
Replace only with part
number specifi ed.
Note:
Les composants identifi és

critiques pour la sécurité.
Ne les remplacer que par
une pièce portant le nu-
méro spécifi é.
• A : B+ Line.
• Voltages and waveforms are dc with respect to ground
under no-signal conditions.
no mark
: POWER ON
*
: Impossible to measure
• Voltages are taken with VOM (Input impedance 10 M).
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.
F : AUDIO
L : USB
a : WIRELESS LAN/Bluetooth
Note 1: When the complete AMP board is replaced, refer to
“SPREADING OF COMPOUND” on page 8.
Note 2: Among mounted electrical parts on each boards, only
parts that are described in the electrical parts list can
be replaced for repair.
The parts that are not described in the electrical parts
list cannot be replaced with single for repairing.
