Be sure to add me to your favorites list NEW Mutec YA-1 12 Volt Power Supply / AC Adapter for Yamaha Keyboards, More PA-1. This is a Mutec YA-1, a perfect substitute for the hard to find Yamaha power supply, the PA-1 or PA-1B. It is NEW, never used, and still in it's original box. This model is used with both professional pieces of gear, and many of the "Home" keyboards, drum machines and the like. I know it's used for instruments like the RY-10 Drum Machine, QY-10 midi music composer, the DX100 synthesizer and accessories like the YME midi merge box, etc. I've used these with all of these electronic instruments, as well as many other models. It is also used for many of the Portasound (PSS- ) model home keyboards, and many of the digital drum pads (DD- ) drum machines as well. This may also work with other manufacturers that use a similar power supply / AC adapter / DC in plug. It has an: output of 12 volts (12V) 0.3 A (300mA) with a positive (+) tip Correct size, barrel type plug Will work on keyboards, synthesizers, midi modules, samplers, effects units, tone generators, drum machines and drum pads, sequencers and more that can accept these specifications.
