1. SafetyPrecautions
1.1. GENERALGUIDELINES
1. Whenservicing, observetheoriginal leaddress. Ifashortcircuit
isfound, replace all parts whichhavebeenoverheatedor
damagedbytheshortcircuit.

2. Afterservicing, see toitthat all theprotectivedevices suchas
insulation barriers, insulation papersshieldsareproperly
installed.
3. Afterservicing, make thefollowing leakagecurrentchecks to
preventthecustomerfrom being exposedtoshock hazards.
1.1.1. LEAKAGE CURRENT COLD CHECK
1. Unplug theACcord and connect ajumperbetweenthetwo
prongson theplug.
2. Measuretheresistance value, withanohmmeter, betweenthe
jumperedACplug and eachexposedmetalliccabinet parton the
equipmentsuchas screwheads, connectors, control shafts, etc.
Whentheexposedmetallicparthas areturn pathtothechassis,
thereading shouldbebetween1M and 5.2 . / Whenthe
exposedmetal does nothaveareturn pathtothechassis, the
reading must be . Fig. 1
1.1.2. LEAKAGE CURRENT HOT CHECK (See Figure1.)
1. Plug theACcord directlyintotheACoutlet. Donotuse an
isolation transformerfor thischeck.
2. Connect a1.5k , 10 watts resistor, inparallel witha0.15 F
capacitors, betweeneachexposedmetallicparton theset and a
good earthground suchas awaterpipe, as showninFigure1.
3. Use anACvoltmeter, with1000 ohms/voltor moresensitivity, to
measurethepotential across theresistor.
4. Check eachexposedmetallicpart, and measurethevoltageat
eachpoint.
5. Reverse theACplug intheACoutlet and repeat eachoftheabove

measurements.
6. Thepotential at anypointshouldnotexceed0.75 volts RMS. A
leakagecurrenttester(Simpson Model 229 or equivalent) maybe
usedtomake thehotchecks, leakagecurrentmust notexceed1/
2milliamp. Incase ameasurementisoutsideofthelimits
specified, thereisapossibilityofashock hazard, and the
equipmentshouldberepairedand recheckedbeforeitisreturned
tothecustomer.
2. Handling the Lead-free Solder
2.1. Aboutleadfree solder(PbF)
Distinction of PbF P.C.B. :
P.C.B.s (manufactured) using leadfree solderwill have a PbF stamp on the P.C.B.
Caution:
-Pbfree solderhas ahighermelting pointthat standard solder;
Typicallythemelting pointis50 -70°F(30 -40°C) higher. / Please
use ahigh temperaturesoldering iron. Incase ofthesoldering
iron withtemperaturecontrol, please set itto700 ±20°F(370 ±
10°C).
-Pbfree solderwill tend tosplashwhenheatedtoo high (about
1100°F/600°C).
-Whensoldering or unsoldering, please completelyremoveall of
thesolderon thepinsor solderarea, and besuretoheat the
soldering points withthePbfree solderuntil itmelts enough.
3. Before Repairand Adjustment
DisconnectAC power, discharge PowerSupplyCapacitors C546, C547, C548, C549 through a
10 , 1 Wresistorto ground.
DONOTSHORT-CIRCUITDIRECTLY(with a screwdriverblade, forinstance), as this may
destroysolidstate devices.
Afterrepairs are completed, restore powergraduallyusing a variac, to avoidovercurrent.
Current consumption atAC 230~240V, 50HzinNOSIGNALmode shouldbe ~400 mA.
4. Protection Circuitry
The protection circuitrymayhave operatedifeitherof the following conditions are noticed:
-Nosound isheard whenthepoweristurnedon.
-Sound stopsduring aperformance.
The function of this circuitryis to prevent circuitrydamage if, forexample, the positive and
negative speakerconnection wires are
“shorted”, orifspeakersystems with animpedance less thanthe indicatedratedimpedance of
the amplifierare used.

Ifthis occurs, followthe procedure outlines below:
1. Turn off thepower.
2. Determinethecause oftheproblemand correct it.
3. Turn on thepoweronce againafteroneminute.
Note :
Whenthe protection circuitryfunctions, the unitwill not operate unless the poweris firstturned
off and thenon again.
5. Connection ofthe Speaker Cables
-Besuretoconnect speakercables beforeconnecting theAC
powersupplycord.
-Theloadimpedance ofanyspeakerusedwiththisunitmust be4
.
-Besuretoconnect thecablefrom therightspeakertotheright
terminal and thecablefrom theleft speakertotheleft terminal.
1. Stripoff theoutercovering, and twist thecenterconductor. Make
surethebareendsofthewires arenotunravelled. (Iftheyare,
twist themtightagain.)
2. Insertthewiretotherearpanel oftheunitand close thelever.
Notes :
-Topreventdamagetocircuitry, nevershort-circuitpositive(+) and
negative(-) speakerwires.
-Besuretoconnect onlypositive(red)wires topositive(+)

terminalsand negative(black) wires tonegative(-) terminals.
6. DisassemblyProcedure
“ATTENTION SERVICER”
Some chassis components mayhave sharpedges.
Be careful whendisassembling and servicing.
1. Thissection describes procedures for checking theoperation of
themajor printedcircuitboardsand replacing themain
components.
2. For reassemblyafteroperation checks or replacement, reverse
therespectiveprocedures.
Special reassemblyprocedures aredescribedonlywhenrequired.
3. Select itemsfrom thefollowing index whenchecks or
replacementarerequired.
