      How to Diagnose Power Supply Failure?
      • The following situations may cause this issue
      • Case 1: The LED on the power supply does not light up; Case 2: Amp/Preamp does not turn on; Case 3: When plugged into the Amp, both light on the amp & power supply start blinking; Case 4: Amp/Preamp make noise; Case 5: Sound shuts off by itself
      • Possible solution
      • Check if the power supply is illuminated when plugged into AC by itself.

        Test the adapter with a meter.

        Try a different power supply (within a range of DC input).

        Test the included power supply on other electrical equipment.
