ABOUT conrad-johnson design

We are a small company offering exclusively audiophile products designed for our

own use as well as our customers'. We believe that our commitment to the purchaser

of our products is nearly unique in the industry. The services we offer to conrad-

johnson owners include:

 

Information - Registered owners of conrad-johnson equipment will be directly
informed of new equipment we have to offer. They will also be informed of any
significant changes in the design of their equipment resulting from our ongoing
development program.

 

Factory updating - Should significant design changes be made, conrad-johnson
design will, whenever practical, offer to update existing equipment. This service
will be offered at a reasonable charge to cover parts, labor, and handling.

 

Factory service - Any conrad-johnson product may be returned to the factory for
service. All equipment serviced at the factory will perform to its published
specifications when returned. Factory service will be offered at reasonable rates.

 

Transferable warranty - conrad-johnson design guarantees its products, not the
owner. Should you decide to sell the product, the warranty may be transferred to
the new owner. (See Registering the Warranty.)

REGISTERING THE WARRANTY

Please return the enclosed card to the factory within 30 days of purchase to register

the warranty. The warranty may be transferred to a new owner if it has been properly

registered initially and if the registered owner sends a signed notice providing the

name and address of the new owner and the model and serial number of the unit.

Proper registration of the warranty is important! Not only will it preserve

transferability of your warranty, it will also enable us to inform you of any alterations

in the design of a given model and of any new products we offer which are likely to

be of interest to you.
