Limited Two-Year Warranty
1. Your new product is covered by a limited two-year warranty
against defects in material and workmanship. Any repairs required
will be made at no charge within the first two years after purchase
as a new unit. This warranty is transferable to new owners within
the original warranty period.
2. Any units returned for warranty repair must be shipped prepaid
after receiving return authorization*. If possible, the unit should be
shipped in its original packaging. If such is not possible, the unit
should be well packed with particular attention paid to protection
of all corners and avoidance of any looseness in the carton.
*Handling and shipping costs are the responsibility of customers
outside the United States.
3. This warranty does not apply to damage resulting from physical
abuse or unauthorized alterations or repairs, or from tube rolling or
adapter use, or from the use of third-party components, or
damage to exterior finish after delivery.
4. The warranty is void if the serial number has been removed,
altered, or defaced.
5. This warranty is void if improper voltage is applied to any input or
output.
6. If Linear Tube Audio determines after receiving the unit that
damage was misrepresented and has been caused by something
not covered by the warranty, the customer must pay for any
necessary repairs before the unit is returned to the customer.
7. Linear Tube Audio reserves the right to improve or change its
products without obligation to modify previously manufactured
units.
