• Note for Printed Wiring Boards and Schematic Diagrams
Note on Printed Wiring Board:
• X : parts extracted from the component side.
• Y : Parts extracted from the conductor side.
• : Pattern from the side which enables seeing.
(The other layer's patterns are not indicated.)
Caution:
Pattern face side: Parts on the pattern face side seen
(Conductor Side) from the pattern face are indicated.
Parts face side: Parts on the parts face side seen from
(Component Side) the parts face are indicated.
• MOTHERBOARD board is multi-layer board.
However, the patterns of intermediate layers have not
been included in diagrams.
• Indication of transistor.

Note 1: When the MS-476 board is defective, exchange the
entire LOADING COMPLETE ASSY (T).
Note 2: When the complete DAMP board is replaced, refer to
"NOTE OF REPLACING THE IC1001 ON THE DAMP
BOARD AND THE COMPLETE DAMP BOARD" on
servicing notes (page 5).
Note 3: When the C1126, C1127, C1128, C1129, C1142,
L1010 and RY001 on the DAMP board are replaced,
spread the bond referring to "BOND FIXATION OF
ELECTRIC PARTS" on servicing notes (page 6).

Note on 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 Ω and
1 / W or less unless otherwise

• Components for right channel have same values as for
left channel. Reference numbers are coded from
• C : panel designation.
Note: The components identifi ed by mark 0 or dotted line
with mark 0 are critical for safety.
Replace only with part number specifi ed.
• A : B+ Line.
• Voltage and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
no mark : TUNER
• Voltages are taken with a 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.
• Signal path.
