• Note for Replacement of the Transistors
The transistors Q113, 114, 116, 117, 119, 120, 213, 214, 216, 217,
219 and 220 have two different ranks: P rank and Y rank.
The rank of these transistors need to be selected properly according
to each channel. When replacing any one of these transistors, check
its rank and replace with the appropriate transistor of the same rank.

DISCRIMINATION:
THIS NOTE IS COMMON FOR PRINTED WIRING
BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is
printed in each block.)
for schematic diagram:
• 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 
 and 
1
/
4
 
W or less unless otherwise
specified.
A
: B+ Line.
B
: B– Line.
• Power voltage is dc 14.4V and fed with regulated dc power
supply from +12V and REM terminals.
• Voltage is dc with respect to ground under no-signal
condition.
• Voltages are taken with a VOM (Input impedance 10 M
).
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
: AUDIO
for printed wiring boards:
• X
: parts extracted from the component side.
: Pattern from the side which enables seeing.
Note: The components identified by mark 
0
 or dotted line
with mark 
0
 are critical for safety.
Replace only with part number specified.
