Warranty

mpernet amplification offers a 2-year warranty on all our products, except on vacuum tubes which are covered by a limited 90-day warranty.
In the unlikely event of a failure or malfunction, please contact our technical support using the contact form on this website before returning the product to us for repair. When the product has been sent to us to our workshop at the sender's cost, we will repair or replace the defective product and send it back usually within 4 weeks (shipping not included). The product needs to be accompanied by a copy of your receipt or invoice, serial number, return address, phone number, e-mail address and a brief description of the problem. Please note that we cannot replace a product until we have received it here in our workshop.

The warranty is lost if the product has been damaged by alteration, misuse, accident, neglect or if the product has been repaired or serviced by persons not authorized by mpernet amplification.
