Service And Care - Cary Audio Design SLI 80 Owner's Manual

SERVICE AND CARE ________________________________________________

The chassis may be cleaned with a soft towel and Windex® or a similar window cleaner. Spray it on the
cleaning cloth to moisten it, not on the component. Do not use solvents or harsh chemicals to clean the
preamplifier. They may remove the labels from the chassis. The frequency and need of cleaning will be
governed by operating environmental conditions. Avoid letting the component become dusty or wet. A
'feather duster' type cleaner will also work well for cleaning the component.
Tube Replacement
If it becomes necessary to replace the tubes in the SLI 80 amplifier, a matched quartet set of output tubes
of the same brand should be used. A new tube kit is available from Cary Audio Design. You should get a
few years or more from the output tubes with everyday usage and many, many years of use from the 6922
& 6SN7 input tubes.
Factory Service
Careful consideration has been given to the design of this product to keep maintenance problems to a
minimum. If the problem is not easily solved, we suggest that you contact our Customer Service
Department by phone at (919) 355-0010, 1–5 pm Eastern Standard Time, to describe your problem in
detail. DO NOT return the component to the factory without a Return Authorization Number (RA) from
the Customer Service Department.
Cary Audio Design assumes no responsibility if the transportation company refuses to pay a damage claim
due to your improper packing or lack of insurance should the unit be lost in shipment. We strongly
suggest using the original packing cartons for shipping any Cary Audio Design component.
