Important Notes
  • The bench fee is credited toward the final repair cost if service is approved.
  • Rush service prioritizes your amp to reach the bench; parts lead times can still affect completion.
  • Certain complex jobs or deep diagnostics may require a 2× bench fee.
  • Lead times and service rates are subject to change—please confirm current terms when submitting your repair.
