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 responsi-
bility 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 infor-
mation necessary for return shipment. The cost of return
shipment is the responsibility of the purchaser.
