We strive to provide excellent customer service and the highest quality repairs possible.


  • All repairs must have the minimum bench/estimate fee paid at the time of drop off.  (see Rates page for details)
  • If you decline to collect the equipment within 30 days of the completion of service or decline the service you will be billed a $5 per day storage fee for up to 60 days. At the end of 60 days your equipment will be considered abandoned and within Desert Amplifier Repair’s legal rights to dispose of/or sell to recoup loss of services provided.
  • Once applied, storage fees can not be waived.
  • Any balance owed on outstanding invoices will be sent to collections. In the event it becomes necessary to enter small claims court, court fees, legal fees, and any loss of wages will be added to the amount owed.
  • Any equipment left past 90 days after the date of completed repair with an unpaid balance will be deemed abandoned and become property of Desert Amplifier Repair.  If you decide to surrender an item for disposal you must complete and return a surrender form.  Surrender forms are available by request in person during business hours, or by email at Surrendering an item does not remove your responsibility to pay the minimum diagnosis fee. 
  • Repairs with parts totaling in excess of $149.99 will require the parts be paid in full as well as any shipping charges prior to the repair, leaving the balance of labor at time of collection.
  • Special order Items must be paid in full prior to ordering regardless of amount.  Please note that shipping costs for special order items are often not provided until after the order is placed.  Any unpaid shipping costs must be paid in full at time of collection, or before mailing out.
  • Returned Checks and e-checks will be billed an additional $90 service fee.
  • We do our best at DAR to provide an accurate estimate for the cost of your repair.  While we do our best to hold to this estimate, there are times when after or during the repair we discover more repairs are necessary.  For example, after replacing weak/failed electrolytic capacitors in vintage amplifiers, oftentimes the new strong voltages can force other weak components to prematurely fail. If the repair amount is within 10-15% percent of the estimated repair cost, in order to maintain our schedule and expedite the repair we will likely complete the repair and adjust the final bill. If the cost is going to exceed 15% of the total estimate we will stop work and provide an additional estimate for the cost of the service.  In the event you decline the additional services you will be billed for parts and labor up to the point when the repair was stopped.


  • Every service includes Desert Amplifiers Repair’s 30 day warranty from the completion of the repair guaranteeing all labor (“Workmanship”) of installations and modifications to be free of defects. Warranty is void if amplifier is tampered with. Desert Amplifier Repair is not liable for manufacturer defects, misuse, or damages caused in travel. ALWAYS follow the manufacturers safety warnings! All sales are final, no exceptions. Many components necessary for the repair of vintage equipment are custom ordered or out of production and purchased from private sellers, for this reason it’s not possible to accept returns. We go above and beyond to do our best to test and grade NOS components prior to installation to prevent failures.  NOS Components will only be used with owners consent.  All other repairs are done with NEW production components.
  • Some new production tube manufacturers offer a warranty on an individual basis and the warranty is subject to the manufacturer’s guidelines and policies.
  • As an authorized service center, we honor the manufacturer’s warranty on warranty service repairs, or DAR’s printed warranty, whichever is longer.
