Maintenance
Vacuum Tubes
It is recommended that you replace the vacuum tubes of your Reference 160S in sets. All of the
tubes in your amplifier have been matched to have similar operating characteristics, to provide the
best sound quality and reliability. In the event you need to replace a single output tube, please refer
to the numbers written on the silver base at the bottom of the vacuum tube when placing an order.
KT150 tubes should be replaced at approximately 3000 hours. 6H30 tubes should be replaced
before 4000 hours.
Servicing
Because of its careful design and exacting standards of manufacture, your Reference 160S
amplifier should normally require only minimal service such as periodic tube replacement to
maintain its high level of performance. Warning: Tube replacement shall be done by skilled or
service personnel, or qualified technician.
Caution
Your Reference 160S amplifier contains sufficient levels of voltage and current to be lethal. Do
not tamper with a component or part inside the unit. Even with the power turned off, a charge
remains in the energy storage capacitors for some time. Refer any needed service to your
authorized Audio Research dealer or other qualified technician. If you have additional questions
regarding the operation, maintenance or servicing of your amplifier, please contact the customer
Support Department of Audio Research Corporation at service@audioresearch.com or call
763-577-9700. You may also initiate a service request by visiting the Audio Research website
(www.audioresearch.com) and selecting ‘Service Repair’ from the drop-down window under
“SUPPORT” on the home page.
Cleaning
The Reference 160S uses two bottom- cover-mounted ultra-quiet fans for forced air cooling of
internal components. Over time, depending upon the environment in which the Reference 160s is
installed, dust will build up inside the chassis that may impede proper cooling, which could reduce
component life. Audio Research therefore strongly recommends the owner have the Reference
160S cleaned of internal dust buildup every: Two years of operation, or when the vacuum tube sets
are replaced –whichever occurs first. Please contact your authorized Audio Research dealer, service
center, or service@audioresearch.com for instructions and assistance with this cleaning operation.
To maintain the new appearance of this amplifier, occasionally wipe the aluminum front panel
with a soft damp (not wet) microfiber cleaning cloth to remove dust. A mild non-alkaline soap
solution may be used to remove fingerprints or similar smudges. To clean the transparent meter
panel, use moist disposable eyeglass wipes designed for coated plastic lenses. Do not apply
pressure with a dry cloth. Cleaners containing abrasives should not be used as they will damage the
anodized finish of the front panel and the transparent meter panel.
