Normally you would need to turn the voltage up high to get the motor running. Then you would lower the voltage back down to your normal operating voltage.
This Adapter allows you to run the machine at the normal voltage you run your machine. No more big Star Up Cord or Hassles adjusting your voltage.
This newer design is company and is used for power supply with a Phono Plug Input.
