Limited Warranty
Audio Research Corporation products
are covered by a 3-Year Limited
Warranty, or a 90-Day Limited Warranty
(vacuum tubes). This Limited Warranty
initiates from the date of purchase, and
is limited to the original purchaser, or in
the case of demonstration equipment,
limited to the balance of warranty
remaining after original shipment to the
retailer or
importer.
In the United States, the specific terms,
conditions and remedies for fulfillment of
this Limited Warranty are listed on the
warranty card accompanying the
product in its shipping carton, or may be
obtained from the authorized retailer or
from the Audio Research Customer
Service Department. Outside the United
States, the authorized importing retailer
or distributor has accepted the
responsibility for warranty of Audio
Research products sold by them.
The specific terms and remedies for
fulfillment of the Limited Warranty may
vary from country to country. Warranty
service should normally be obtained
from the importing retailer or distributor
from whom the product was purchased.
In the unlikely event that technical
service beyond the ability of the
importer is required, Audio Research will
fulfill the terms and conditions of the
Limited Warranty. Such product must be
returned at the purchaser's expense to
the Audio Research factory, along with
a photocopy of the dated purchase
receipt for the product, a written
description
of the problem(s)
encountered, and any information
necessary for return shipment. The cost
of return shipment is the responsibility of
the purchaser.
