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.

f
: Internal component.
• 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

une pièce portant le nu-
méro spécifi é.
• A : B+ Line.
• Power voltages is dc 14.4V and fed with regulated dc
power supply from ACC and BATT cords.
• Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.

• 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.

Note: When the complete MAIN board is replaced, the des-
tination setting is necessary. Refer to “DESTINATION
