What to do if my Alesis Amplifier has no power?

  Keith WilliamsJul 25, 2025
  If your Alesis Amplifier has no power, meaning no LED and no fan, it could be due to a tripped or faulty breaker. Try resetting the breaker first. If that doesn't work, the breaker might need replacement. Other potential causes include a faulty transformer, which would require replacing the transformers and retesting, or an issue with the A.C. Be sure that a 30 amp service is available without significant voltage drop.

  If the Clip LED is on but there's no output from your Alesis Amplifier, this could be due to a blown output section. In this case, replace all active components following the diver I.C. (U2-channel A U3 channel B) in the blown channel. Also, replace any out of tolerance resistors in the output section. Another cause might be poor solder on the large power supply capacitors, which causes ground reference to drift, so troubleshooting and repair would be necessary. Also check if J1 or J14 are loose, if so, reseat the cable and apply hot glue to prevent re loosening.

Why Alesis Amplifier has no output, no LED, but Fan running full on?

  Christopher ParkAug 15, 2025
  If your Alesis Amplifier has no output, no LED, but the fan is running full on, it could be due to a disconnected fan board or main harness. Try reconnecting and retesting. It could also be a faulty +15V regulator, which would require troubleshooting and repair.
