IMPORTANT

The user is responsible for notifying his or her Krell deal- er, distributor, or Krell that a tube preamplifier will be used with the Full Power Balanced amplifier, so that the Krell dealer, distributor, or Krell can activate the coupling capac- itors. If the user does not notify the Krell dealer, distributor, or Krell and uses a tube preamplifier without the Full Power Balanced amplifier’s coupling capacitor engaged, Krell reserves the right to refuse warranty related service due to DC-related damage.

Proof of purchase in the form of a bill of sale or receipted invoice substantiating that the unit is within the warranty period must be presented to obtain warranty service. The warranty begins on the date of the original retail purchase, as noted on the bill of sale or receipted invoice from an authorized Krell dealer or distributor. Previously owned equipment, when re-purchased from an authorized Krell dealer or distributor, has the balance of the original war- ranty, based on the original date of manufacture.

The warranty for Krell products is valid only in the country to which they were originally shipped, through the authorized Krell distributor for that country, and at the factory. There may be restrictions on or changes to Krell’s warranty because of regulations within a specific country.

If a unit is serviced by a distributor who did not import the unit, there may be a charge for service, even if the product is within the warranty period.

If you have purchased your Krell product outside the U.S.A. and wish to have it serviced at the factory, all freight and associated charges to the factory are your responsibility. Krell will pay return freight to the U.S.A.-based freight for- warder of your choice. Freight and other charges to ship the unit from the freight forwarder to you are also your respon- sibility.

Krell is not responsible for any damage incurred in transit. Krell will file claims for damages as necessary for units dam- aged in transit to the factory. You are responsible for filing claims for shipping damages during the return shipment.

Krell does not supply replacement parts and/or products to the owner of the unit. Replacement parts and/or products will be furnished only to the distributor performing service on this unit on an exchange basis only; any parts and/or prod- ucts returned to Krell for exchange become the property of Krell.

No expressed or implied warranty is made for any Krell product damaged by accident, abuse, misuse, natural or personal disaster, or unauthorized modification.
