16V AC Power Adapter for Yamaha PA-300 PA-301 PA-300B PA-300C PA300C Arranger Workstation: UL Listed Extra Long Supply Cord for Yamaha PSR-S670 PSR-A3000 PSR-S975 PSR-S775 PSR-S900

I needed a replacement power supply for a Yamaha Motif Rack-XS. The page clearly states that this power supply will operate a Motif Rack-ES and Rack-XS. I give the power brick two stars because it operates appropriately and within spec, but it does not interface with the Motif Rack-XS ( or Rack-ES, for that matter.) The center pin on the Motif units is too large for the barrel jack on the power supply. I will get a few adapters to see if I can get it to work and will report back.

I originally bought another brand and though they claim it is a direct replacement for Yamaha PA300, what they sent me only output 1.4 amps. So I ordered this unit. This unit is much sturdier and produces over 4 amps. I've only had it a couple hours but am impressed with its construction.

worked as promised.
