Vacuum Tubes
It is recommended that you replace the
vacuum tubes of your Reference 750 SE 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.
Servicing
Because of its careful design and exacting
standards of manufacture, your Reference
750 SE amplifier should normally require only
minimal service to maintain its high level of
performance.
Caution
Your Reference 750 SE 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.

Maintenance
Cleaning
To maintain the new appearance of this
amplifier, 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, the
recessed nameplate and other features of
the front panel.

not place in landfill. In accordance with the
