5、NFORMATION IN SERVICE LITERATURE. 1-2 SERVICING PRECAUTIONS CAUTION:Before servicing the Stereo amplifier covered by this service data and its supplements and addends, read and follow the SAFETY PRECAUTIONS. NOTE: if unforeseen circumstances create conflict between the following servicing precaution
6、s and any of the safety precautions in this publication, always follow the safety precautions. Remember Safety First: General Servicing Precautions 1.Always unplug the Stereo amplifier AC power cord from the AC power source before: (1) Removing or reinstalling any component, circuit board, module, o
7、r any other assembly. (2) Disconnecting or reconnecting any internal electrical plug or other electrical connection. (3) Connecting a test substitute in parallel with an electrolytic capacitor. Caution:A wrongpartsubstituteorincorrectpolarity installation of electrolytic capacitors may result in an
8、explosion hazard. 2.Do not spray chemicals on or near this Stereo amplifier or any of its assemblies. 3.Unless specified otherwise in this service data, clean electrical contacts by applying an appropriate contact cleaning solution to the contacts with a pipe cleaner, cottontipped swab, or comparabl
9、e soft applicator. Unless specified otherwise in this service data, lubrication of contacts is not required. 4.Do not defeat any plug/socket B+ voltage interlocks with which instruments covered by this service manual might be equipped. 5.Do not apply AC power to this Stereo amplifier and/or any of i
10、ts electrical assemblies unless all solid-state device heat sinks are correctly installed. 6.Alwaysconnecttestinstrumentgroundleadtothe appropriate ground before connecting the test instrument positive lead. Always remove the test instrument ground lead last. Insulation Checking Procedure Disconnect
11、 the attachment plug from the AC outlet and turn the power on. Connect an insulation resistance meter (500V) to the blades of the attachment plug. The insulation resistance between each blade of the attachment plug and accessible conductive parts (Note 1) should be more than 1 M-ohm. Note 1: Accessi
12、ble Conductive Parts including Metal panels, Input terminals, Earphone jacks, etc. Electrostatically Sensitive (ES) Devices Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Electrostatically Sensitive (ES) Devices. Examples of
13、typical Es devices are integrated circuits and some field effect transistors and semiconductor chip components. The following techniques should be used to help reduce the incidence of component damage caused by static electricity. 1.Immediately before handing any semiconductor component orsemiconduc
14、tor-equippedassembly,drainoffany electrostatic charge on your body by touching a known earth ground.Alternatively,obtainandwearacommercially available discharging wrist strap device, which should be removed for potential shock reason prior to applying power to the unit under test. 2.After removing a
15、n electrical assembly equipped with ES devices, place the assembly on a conductive surface such as aluminum foil, to prevent electrostatic charge buildup or exposure of the assembly. 3.Use only a grounded-tip soldering iron to solder or unsolder ES devices. 4.Use only an antistatic solder removal de
16、vice. Some solder removal devices not classified a “ anti-static”can generate electrical charges sufficient to damage ES devices. 5.Do not use freonpropelled chemicals. These can generate electrical charge sufficient to damage ES devices. 6.Do not remove a replacement ES device from its protective p
17、ackage until immediately before you are ready to install it. (Most replacement ES devices are packaged with leads electrically shorted together by conductive foam, aluminum foil, or comparable conductive material). 7.Immediately before removing the protective material from the leads of a replacement
18、 ES device, touch the protective material to the chassis or circuit assembly into which the device will be installed. Caution: Be sure no power is applied to the chassis or circuit, and observe all other safety precautions. 8.Minimizebodilymotionswhenhandingunpackaged replacement ES devices. (Normal
19、ly harmless motion such as the brushing together of your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity sufficient to damage an ES device.) 1-3 SPECIFICATIONS GENERAL Power requirements:AC 100-240 V , 50/60 Hz Power consumption: 45W Dimensions (Appro
