6  Warranty Information 

 

6.1 Warranty  Summary 
 

All Stewart Audio amplifiers and accessories, unless excluded in this 
summary, are covered by a 3-year limited warranty on parts and labor 
from the data of purchase. In order to be eligible for warranty repairs, 
the amplifiers and accessories must have been purchased through an 
authorized Stewart Audio dealer and submitted by the original purchas-
er. This warranty is only valid in the country in which the amplifier was 
purchased. 
 

6.1.1 Eligibility Requirements. 

Stewart Audio warrants against all malfunctions which come as a result 
of component or manufacturer defect. The amplifier is also covered 
from all failures which arise during the warranty period (3 years from 
date of purchase) that are not a result of misuse. The following actions 
will void your warranty: 
 



The power cord or AC plug has been damaged through misuse. 



The amplifier has been exposed to moisture or extreme tempera-
tures. 



The amplifier has been dropped, items have been dropped on the 
amplifier, or the enclosure has been damaged. 



The amplifier has been opened by the operator. 



The amplifier was improperly packaged when sending to the fac-
tory for repair, resulting in damage. 



Any of the precautions or instructions found in this manual were 
not followed. 

 
Damages resulting to the amplifier which are not covered under this 
warranty can be factory-repaired at cost to the customer. Use the con-
tact information below to initiate the repair process. 
 

6.2 Return Procedure

Authorization (RA) number. One can be obtained by contacting Stewart 
Audio at (209) 588-8111 or via e-mail at [email protected].  
 

NOTE: Any defective products received without an RA number 
will be returned to sender at their expense.
