YST-SW320 SERVICE MANUAL

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.

AC LEAKAGE
1. Critical Components Information WALL EQUIPMENT TESTER OR
Components having special characteristics are marked Z OUTLET UNDER TEST EQUIVALENT
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 INSULATING
from supply circuits. TABLE

● Meter impedance should be equivalent to 1500 ohm shunted ● Leakage current must not exceed 0.5mA.
by 0.15µF.
● Be sure to test for leakage with the AC plug in both
polarities.

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 REASON 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.

● Installation of power switch

Rapid 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 cord

After 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,

Oscilloscope (dual trace type)

Connection
1) Connect the output signal from the signal generator
to the input terminal of YST-SW320.
2) Disconnect the connector terminal connected to the ● Confirmation of AUTO STANDBY

Setting
1) 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 level
observed at oscilloscope CH2 is 28Vp-p.

Waveform observation
With the settings made as described above, observe
the waveform obtained at CH1 for judgment.
