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 PSU 

, 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.
