1 DP-2 A-397 STERE AMPLIFIER A-397 SERVICE MANUAL 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: IMPRTANT NTICE 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. IMPRTANT: 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). IMPRTANT: Turn the unit FF during disassembly and part replacement. Recheck all work before you apply power to the unit.

WALL UTLET EQUIPMENT UNDER TEST AC LEAKAGE TESTER R EQUIVALENT 2. Leakage Current Measurement (For 2V Models nly) When service has been completed, it is imperative to verify that all exposed conductive surfaces are properly insulated from supply circuits. INSULATING TABLE Meter impedance should be equivalent to ohms shunted by.µf. A V Leakage current must not exceed.ma. Be sure to test for leakage with the AC plug in both polarities.

ATTENTIN F, F2 : UTILISER UN FUSIBLE DE RECHANGE DE MEME TYPE DE 6A, 2V. WARNING: CHEMICAL CNTENT NTICE! 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. D NT PLACE SLDER, ELECTRICAL/ELECTRNIC R PLASTIC CMPNENTS IN YUR MUTH FR ANY REASN WHATSEVER! A-397 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. About Lead Free Solder / The P.C.B.s installed in this unit are soldered using the following solder. Side A SMT REFLW Process Side B Solder Dip MI FLW Process 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) 2

3 DP-2 A-397 A-397 Caution:. As the melting point temperature of the lead free solder is about 3 C to C ( F to 7 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. IMPEDANCE SELECTR REMTE CNTRL PANEL IMPEDANCE SELECTR WARNING: Do not change the setting of the IMPEDANCE SELECTR switch when the unit power is switched on, as doing so may damage the unit.
