Care Care
TT he Model 12 Mono Power Amplifier is finely constructed from pieces
of solid aluminum. The surface of the unit is cut in a unique process
that uses a diamond tipped blade. This process was refined over
many years to produce an artistic and attractive finish. The front,
top, bottom and side panels are then finished with fine automobile
polyurethane clear coat after a light anodizing to preserve the clarity
of the finish and are not raw or exposed metal.
Because the surface is not finished in the typical fashion of most
audio and video equipment, there are a few rules that must be kept
in mind when cleaning the equipment.
• Please allow the unit to cure for 6 months before attempting to
clean it. This will prevent small scratches from marring the
surface before the surface coating has had a chance to harden
completely.
• The top cover, sides, and bottom cover can all be cleaned with
a soft cotton cloth (such as an optical lens cleaning cloth or fine
furniture polishing rag) dampened with plain water. Water should
be applied directly to the cloth and not the chassis. If a mark
has been left on the chassis, do not use any type of abrasive or
chemical cleaner to remove the mark. A very mild plastic or
glass cleaner that does not contain ammonia should be tried
only as a last resort. Please contact the factory before trying any
type of cleanser on the chassis other than water to clean the
unit.
• The front panel of the unit should never be cleaned with anything
other than a very soft cotton cloth and plain water or fine oil-
based furniture wax or polish. Because of the fine finish of the
front panel, small scratches from the use of any other agent to
clean the front panel will become very visible. Again, the water
or polish should be applied to the cloth, not the chassis.
If you have any questions about the treatment or cleaning of your
Model 12 amplifier, please contact your dealer or the Jeff Rowland
Design Group factory before attempting to clean the chassis. The
use of a cleanser or abrasive to clean the chassis that has not been
approved by the factory will almost certainly damage the finish and
will not be covered under warranty.
Maintenance Maintenance
A
A ll Jeff Rowland Design Group products are designed to provide a
lifetime of enjoyment and listening pleasure. The chassis is sealed to
prevent dust from entering and the interior of the chassis should not
need cleaning during the lifetime of the product. All internal circuitry
is self-adjusting or stable so no adjustments or maintenance of any
kind should be necessary over a lifetime of normal operation.
If the amplifier is ever in need of service, updating, or upgrading, it
should only be returned to an authorized repair facility or technician
for servicing. It is not recommended that the customer attempt to
disassemble or repair the unit and doing so may void your warranty.
