Item : B000WS1QC6 Customer Reviews Product meets expectations by .. L. Johnston (England) We purchased this adapter because we needed to convert a UK plug. This adapter is smaller than our UK adapter and works just as expected. Replacement for PA-3BU adapter by .. P. Chau (Los Angeles, CA) I bought this Yamaha PA130MM adapter as a replacement for the old damaged adapter PA-3BU. This new model PA130MM is compatible with the keyboard as well and it is light weight and small. I look around and Amazon got the best price. Came in original Yamaha box (packaging). Works perfectly well. As Advertised by .. M. Baldridge (Los Angeles) It was a real Yamaha power adapter and it works great. The real surprise is how small and light it is. It's about the size and weight of a cell phone adapter. Yamaha power supply by .. Dennis F. Freeze () Works exactly as it should -- a good thing, since my wonderful Yamaha keyboard sucks the batteries dry like nobody's business! Nothing special, just an average power adapter by .. Kevin Schanz (Norco, CA USA) Does exactly what the description says, however in the long run, it's just a very average AC power adapter that can be replaced by any 12V generic one. The cord is too short, I'd estimate around 5-6 feet, so you may have difficulty playing your piano if it isn't up against the wall. (Additionally, it will serve as a tripping hazard if your piano is positioned 3-4 feet away from the wall.)
