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.
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.
• A : B+ Line.
• B : B– Line.
• H : Adjustment for repair.
• Power voltage is dc 14.4 V and fed with regulated dc
power supply from +12 V and REM terminals.
• Voltages are dc with respect to ground under no-signal
conditions.
• Voltages are taken with VOM (Input impedance 10 MΩ).
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.

• Note for Replacement of the Transistors
The transistors Q110, 111, 210, 211, 310, 311, 410 and 411 have
two different ranks: P rank and Y rank.
The rank of these transistors need to be selected properly accord-
ing to each channel. When replacing any one of these transistors,
check its rank and replace with the appropriate transistor of the
same rank.
