MAINTENANCE AND CARE
All 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 the interior of the chassis and thus
should never need interior cleaning during the lifetime of the product. All internal circuitry
is maintenance-free such that no adjustments of any kind are necessary over the lifetime
of the product. 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.
The front panel of the unit is precision-machined in a unique process that incorporates a
diamond tipped cutting tool. This process was refined over many years to produce an
attractive and unique appearance. 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.
NOTE: PLEASE ALLOW THE FRONT PANEL, WHICH IS COATED WITH AN AUTOMOTIVE-GRADE
POLYURETHANE FINISH, 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.
WARNING: 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
POLISH. BECAUSE OF THE FINE FINISH OF THE FRONT PANEL, USE OF ANY OTHER CLEANING
AGENT MAY PERMANENTLY SCRATCH THE FINISH.
The top and bottom cover, sides and bottom are protected by a durable black anodized
finish and can be cleaned with a soft cotton cloth (such as an optical lens or microfiber
cleaning cloth) dampened with plain water. Water should be applied directly to the cloth
and not the chassis. A very mild plastic or glass cleaner that does not contain ammonia
may also be used. If a mark has been left on the chassis, do not use any type of
abrasive or chemical cleaner to remove the mark.
If you have any questions about the care or cleaning of your MODEL 735
MONOBLOCK AMPLIFIERS, please contact your dealer 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.
