This manual has been provided for the use of authorized YAMAHARetailers and their service personnel.It has been assumed that basic service procedures inherent to the industry,and more specifically YAMAHA Products, are already known andunderstood by the users, and have therefore not been restated.

WARNING: Failure to follow appropriate service and safetyprocedures when servicing this product may result inpersonal injury, destruction of expensive components,and failure of the product to perform as specified. Forthese reasons, we advise all YAMAHA product ownersthat any service required should be performed by anauthorized YAMAHA Retailer or the appointed servicerepresentative.

IMPORTANT: The presentation or sale of this manual to any individualor firm does not constitute authorization, certificationor recognition of any applicable technicalcapabilities, or establish a principle-agent relationshipof 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 departmentsof YAMAHA are continually striving to improve YAMAHA products.Modifications are, therefore, inevitable and specifications are subject tochange without notice or obligation to retrofit. Should any discrepancyappear to exist, please contact the distributor's Service Division.

WARNING: Static discharges can destroy expensive components.Discharge any static electricity your body may haveaccumulated by grounding yourself to the ground bussin the unit (heavy gauge black wires connect to thisbuss).

IMPORTANT: Turn the unit OFF during disassembly and partreplacement. Recheck all work before you apply powerto the unit.

TO SERVICE PERSONNEL

1. Critical Components InformationComponents having special characteristics are marked Zand must be replaced with parts having specifications equalto those originally installed.

2. Leakage Current Measurement (For 120V Models Only)When service has been completed, it is imperative to verifythat all exposed conductive surfaces are properly insulatedfrom supply circuits.

Meter impedance should be equivalent to 1500 ohm shuntedby 0.15µF.

WARNING: CHEMICAL CONTENT NOTICE!The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and/orplastic (where applicable) components may also contain traces of chemicals found by the California Health andWelfare 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 FORANY REASON WHATSOEVER!

Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumesor expose eyes to solder/flux vapor!

If you come in contact with solder or components located inside the enclosure of this product, wash your handsbefore handling food.

DISASSEMBLY PROCEDURES(Remove parts in the order as numbered.)

1. Removal of Front Panel Ass'yRemove 4 screws ( q ) and then remove the FrontPanel Ass'y in Fig. 1.

* Use an Allen wrench (3mm) to unscrew the FrontPanel Ass'y.

Fig. 2

Fig. 1

* When assembling the Rear Panel, check to ensure that

the gasket is not damaged so as to prevent air leakage

from occurring.

2. Removal of Loud Speakera. Remove 8 screws ( w ) and then remove the Base

Ass'y in Fig. 2.b. Remove 4 screws ( e ) and then remove the Loud

Speaker in Fig. 2.

3. Removal of Rear Panel Ass'yRemove 12 screws ( r ) in Fig. 3.

* Arrow marks ( ) are printed to identify the screws to be

removed.

Installation of emblem1. Put the emblem into the cabinet at the specified posi-

tion.

2. Place a piece of cloth/wood on top of the emblem.

3. Using a mallet, hammer the emblem in place through

the cloth/wood.* Use special care not to cause damage to the emblem or

cabinet while hammering the emblem.

Installation of power switchRapid cures bond (such as 5 minute epoxy) is required to fix the power switch.

As shown in Fig. A, apply rapid cures bond (such as 5 minute epoxy) to the power switch (the area which

contacts the rear panel), insert it in the rear panel and make sure it is fixed.

(Inserting the power switch in the rear panel only would not be sufficient for its secure installation.)

Precaution for installation of power cordAfter connecting the power cord, be sure to apply the rapid cures bond (such as 5 minute epoxy) to the

cord stopper as shown in Fig. A,

ADJUSTMENTS

Idling AdjustmentTo stabilize operation of the amplifier, turn ON thepower with no input signal and wait for 1 or 2 minutesin non loaded condition before the adjustment.Adjust VR1 so that the voltage between terminalsTP11 and TP12 is DC 50mV to 250mV.

Confirmation of Power Amp operationFor the power amplifier which has been repaired, itis absolutely necessary to confirm that a correctwaveform is obtained at points indicated by A and Bin the schematic diagram according to the followingprocedure.

Devices requiredSignal generator8Ω or 6Ω load resistorOscilloscope (dual trace type)

Connection1) Connect the output signal from the signal generator

to the input terminal of YST-SW320.2) Disconnect the connector terminal connected to the

speaker unit and reconnect it to the load resistor.3) Connect the HOT side of the oscilloscope CH1 probe

to the point A or B indicated in the figure and theGND side to the GND of the main unit.

4) Connect the oscilloscope CH2 input to the red sideof the connector cable, which is connected with theload resistor.At this time, the GND terminal of CH2 must be leftunconnected.

Setting1) Set the signal generator to the sine wave, 100Hz and

minimum output level settings.2) Set the volume of YST-SW320 to the minimum

position.3) Turn on the power to YST-SW320.4) Adjust the output level of the signal generator and the

volume of YST-SW320 so that the output levelobserved at oscilloscope CH2 is 28Vp-p.

Waveform observationWith the settings made as described above, observethe waveform obtained at CH1 for judgment.
