IMPORTANT NOTICE
This manual has been provided for the use of authorized YAMAHA Retailers and their service personnel.
It has been assumed that basic service procedures inherent to the industry, and more specifically YAMAHA Products, are already
known and understood by the users, and have therefore not been restated.
WARNING: Failure to follow appropriate service and safety procedures when servicing this product may result in personal
injury, destruction of expensive components, and failure of the product to perform as specified. For these reasons,
we advise all YAMAHA product owners that any service required should be performed by an authorized
YAMAHA Retailer or the appointed service representative.
IMPORTANT: The presentation or sale of this manual to any individual or firm does not constitute authorization, certification or
recognition of any applicable technical capabilities, or establish a principle-agent relationship of any form.
The data provided is believed to be accurate and applicable to the unit(s) indicated on the cover. The research, engineering, and
service departments of YAMAHA are continually striving to improve YAMAHA products. Modifications are, therefore, inevitable
and specifications are subject to change without notice or obligation to retrofit. Should any discrepancy appear to exist, please
contact the distributor's Service Division.
WARNING: Static discharges can destroy expensive components. Discharge any static electricity your body may have
accumulated by grounding yourself to the ground buss in the unit (heavy gauge black wires connect to this buss).
IMPORTANT: Turn the unit OFF during disassembly and part replacement. Recheck all work before you apply power to the unit.

WARNING: CHEMICAL CONTENT NOTICE!
The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and/or plastic (where
applicable) components may also contain traces of chemicals found by the California Health and Welfare Agency (and
possibly other entities) to cause cancer and/or birth defects or other reproductive harm.
DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY REA-
SON WHATSOEVER!
Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or expose
eyes to solder/flux vapor!
If you come in contact with solder or components located inside the enclosure of this product, wash your hands before
handling food.

■TO SERVICE PERSONNEL
1. Critical Components Information
Components having special characteristics are marked s
and must be replaced with parts having specifications equal
to those originally installed.
2. Leakage Current Measurement (For 120V Models Only)
When service has been completed, it is imperative to verify
that all exposed conductive surfaces are properly insulated
from supply circuits.
●Meter impedance should be equivalent to 1500 ohms
shunted by 0.15µF.
●Leakage current must not exceed 0.5mA.
●Be sure to test for leakage with the AC plug in both polarities.

無鉛ハンダにはいくつかの種類がありますが、修理時には
下記のような無鉛ハンダの使用を推奨します。
・Sn+Ag+Cu（錫+銀+銅）
・Sn+Cu（錫+銅）
・Sn+Zn+Bi（錫+亜鉛+ビスマス）
注意：
① 無鉛ハンダの融点温度は通常の鉛入りハンダに比べ30
〜40℃程度高くなっていますので、それぞれのハンダ
に合ったハンダごてをご使用ください。
② 鉛入りハンダを使わざるを得ない場合は、あらかじめ交
換する部品端子部やその周辺部の無鉛ハンダをすべて取
り除くか、あるいは無鉛ハンダと鉛入りハンダが十分に
溶けた状態となるようにハンダ付けしてください。
Among some types of lead free solder currently available,
it is recommended to use one of the following types for the
repair work.
• Sn + Ag + Cu (tin + silver + copper)
• Sn + Cu (tin + copper)
• Sn + Zn + Bi (tin + zinc + bismuth)
Caution:
1. As the melting point temperature of the lead free solder
is about 30°C to 40°C (50°F to 70°F) higher than that of
the lead solder, be sure to use a soldering iron suitable
to each solder.
2. If lead solder must be used, be sure to remove lead free
solder from each terminal section of the parts to be
replaced and from the area around it completely before
soldering, or make sure that the lead free solder and
lead solder melt together fully.
The P.C.B.s installed in this unit are soldered using the
following solder.

■DISASSEMBLY PROCEDURES / 分解手順
(Remove parts in the order as numbered.)
Cautions for disassembly and reassembly :
• Disconnect the power cable from the AC outlet.
• Spread soft cloth or the like and perform the work on it.
• Use full care as you may be injured by the front grille
or other part.
• All screws must be tightened securely to prevent air
leakage. Check the number of screws and their
positions when installing them.
• When installing parts, be careful not to have anything
such as cables caught between other parts.
• Make sure that all the removed driver (tweeter) parts
are reinstalled at specified positions.

When checking the P.C.B. :
• The Rear Unit removed from the unit does not work
because its grounding is loose. Be sure to connect the
ground of the Rear Unit to the chassis or GND with a
lead wire or the like. (Fig. A)
• Reconnect all cables (connectors) that have been
disconnected.
Be sure to use the extension cable for servicing for the
following section.
DSP P.C.B. CB300 – INPUT (2) P.C.B. CB9 :
MFA27160 (27P 160mm)
DSP P.C.B. CB1, CB2 – AMP P.C.B. CB3 :
MFA18160 (18P 160mm)
• When connecting the cable, use care for the polarity.
2. Removal of Rear Unit
a. Remove 22 screws (3). (Fig. 2)
b. Remove CB7, CB10 and CB14. (Fig. 3)
