I was at my morning show, and my keyboard would not turn on. I keep a spare adapter in my car (but no a spare keyboard), so I prayed that it was the adapter. Luckily, it was.

As the keyboard is less than a year old, the adapter is under warranty. I just faxed a copy of my receipt to Yamaha, and they are going to replace it.

I did notice the extremely cheap PA300 adapters available on Ebay. It's definitely the wise thing to have a back up.
