Maintenance
Vacuum Tubes
It is recommended that you replace the
6H30 vacuum tubes of your DAC9 in
sets. All of the tubes in your converter
have been matched to have similar
operating characteristics, to provide
the best sound quality and reliability.
Servicing
Because of its careful design and exacting
standards of manufacture, your DAC9
converter should normally require only
minimal maintenance to maintain
its high level of performance.
Should you need service, please contact
your authorized Audio Research dealer.
For additional questions regarding the
operation, maintenance or servicing of your
converter, please contact the Customer
Support Department of Audio Research
Corporation at
service@audioresearch.com or call
763-577-9700. You may also initiate service
by visiting the Audio Research website
(www.audioresearch.com) and
selecting ‘Service Repair’ at the
top right of the home page.
Caution
Your DAC9 converter 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 hours, or even days.
Cleaning
To maintain the new appearance of this
converter, occasionally wipe the front panel
and top cover with a soft, damp (not wet)
cloth to remove dust. A mild, non-alkaline
soap solution may be used to remove
fingerprints or similar smudges. Cleaners
containing abrasives should not be used
as they will damage the anodized finish of
the front panel. A small, soft paintbrush
is effective in removing dust from bevels,
and other features of the front panel.
