Limited Warranty

 

Palstar Inc. warrants the Commander II to be free from defects in material and workmanship 

under normal use and service 

for a period of one (1) year from the date of delivery to the 

first buyer

 (the “Warranty Period”). Palstar Inc.’s obligation under this warranty is limited to 

repair or replacement of the product at it’s option at the Palstar factory in Piqua, OH.  

This warranty is effective only when the product is returned to the factory with all transpor-

tation charges prepaid and examination of the product discloses, in Palstar’s judgment, to have 
been defective during the Warranty Period.  

The Warranty Period shall not extend beyond its original term with respect to interim in-

warranty repairs by Palstar. This Warranty Period shall not apply to any product which has been 
repaired or altered by anyone other than Palstar without prior written authorization. Warranty 
does not extend to any products which have been subject to damage from improper installation, 
application or maintenance in accordance with the operating specifications. Palstar neither as-
sumes nor authorizes any person to assume for it any obligation or liability other than herein 
stated. 

 

Shipping Your Amplifier Back to the Factory

 

Due to the necessity of shipping the amplifier with the HV transformer removed,  please 

contact the factory for instructions before sending an amplifier back to us.  There are circum-
stances in which it may not be necessary to return the HV transformer, thereby saving you ship-
ping charges.  When you call, Palstar will inform if transformer return is necessary.  If trans-
former return is necessary, remove it from the amplifier cabinet and ship it separately, prefera-
bly in its original crate.

 

 

Repair Policy

 

When sending in a product for service, see the section above. If not using the original pack-

ing materials, please “double” box it carefully and ship it insured for your protection. Please 
include a note clearly describing the problem, how you wish the item returned and how you 
wish to pay for the service. Package your unit properly. Palstar, Inc. is not responsible for mer-
chandise damaged in shipment. Our service rate is $30 per hour (1/2 hr. minimum). 

 

Return Policy

 

All returns must receive prior authorization from Palstar. Returned items must be received in 

original—AS SHIPPED—condition including the original box, manuals, accessories, and copy 
of sales receipt. Returns must be within 14 days of purchase. Returned items are subject to a 
25% restocking fee. Shipping is not refundable.
