Bundle the core wound on the lead line of AC inlet into the
hole of the shown hole with the nylon band.
When bundling, put the head of the nylon band in the set.
The core mounting direction is as shown.
After bundling, insert CNS501 into CNP501.

(CNP501)

Nylon Band

Check the line process.

The cored lead line soldered on the AC Inlet 
is processed as specified.

Pass the ground line of AC Inlet 
through the edge side, and 
bundle it in the shown direction.

Edge Saddle

As shown, route the lead line under POWER 
SW and through the front edge saddle, and 
project it on the chassis side. Also retain the 
long lead line at 4 places and the short one at 
2 places with the clamper. Pass the short one 
through the center saddle. 

Pass three kinds of the shown lead lines 
(CNS902, CNS906 and CNS905) through the 
edge saddle from the front panel to the outside.

Check the line process.

The lead line soldered on POWER-SW is processed as specified.

Core mounting and line process illustration

Before installing the core process hardware, attach the 
core to the lead line from the front panel.
Pass the nylon band through the hole of the core process 
hardware, and fasten the core.
(The head of the nylon bond must not be positioned on 
the upper side.)
(Take care for the front and rear sides of the core process 
hardware.) 

After the process, install the core process hardware.

Bundle CNP102 (3P) on the core process 
hardware with nylon band.
Process the lead line on the chassis side.
Don't direct the head of the nylon band upward.

Pull up CNS902 which is passed 
under, and insert it into CMP807.

Insert CNS803 to CNP803.

Only CNS902 inserted to CNP697
is processed with the edge saddle 
and clamper.

Process CNS906 from the front panel 
with the edge saddle of Area A, and 
insert it into CNP804.

Since CNS902 is thick, don't process it with the clamper 
of Area B, and bundle it on CNS906 and CNS905 with 
nylon band (X2). Don't direct the head of the nylon band 
upward.

Process CNS906 and CNS905 on the clamper of Area B.

Using the nylon band, scoop up all lead lines 
processed with the core and bundle them.

After the line is processed, the connectors CNWAM1B, CNWAM28, 
CNWAM1C and CNWAM2C must not be retained with the core or lead line.

As shown, bundle A after passing the doubly stacked upper core through 
the hole on the side of the bottom shield of 1-bit amplifier.

 The indicated voltage in each section is the one measured

by Digital Multimeter between such a section and the chas-
sis with no signal given.
1. In the tuner section,

(  ) indicates AM
< > indicates FM stereo

2. In the main section, a tape is being played back.
3. In the deck section, a tape is being played back.

(  ) indicates the record state.

4. In the power section, a tape is being played back.
5. In the CD section, the CD is stopped.

•

 Parts marked with “       ” (                          ) are important for

maintaining the safety of the set. Be sure to replace these
parts with specified ones for maintaining the safety and
performance of the set.

•

 Resistor:

To differentiate the units of resistors, such symbol as K and
M are used: the symbol K means 1000 ohm and the symbol
M means 1000 kohm and the resistor without any symbol is
ohm-type resistor. Besides, the one with “Fusible” is a fuse
type.

•

 Capacitor:

To indicate the unit of capacitor, a symbol P is used: this
symbol P means micro-micro-farad and the unit of the
capacitor without such a symbol is microfarad. As to
electrolytic capacitor, the expression “capacitance/withstand
voltage” is used.
(CH), (TH), (RH), (UJ): Temperature compensation
(ML): Mylar type
(P.P.): Polypropylene type
