we bought my Grandson a Yamaha keyboard for Christmas but it didn't come with a power adapter. It calls for a Output: DC 12v, 1.0Amp, I have a Output: DC 12v, 500ma adapter and want to know if this will work. thanks for any info.

I might work but i would not recommend it, under powering a electronic device can do as much damage as over powering it. Its also equally important to make sure the power adapters polarity matches your keyboards ie: center positive or center negative.

If you can't find something with specs to match, you can try checking sites like these:

http://www.kraftmusic.com/digital-pianos-and-keyboards/keyboard-accessories/power-adapters/?p=2

The first product I clicked on at the Yamaha link was the PA130, and the other two links list it as well. Specs and model compatibility indicated within the link below:

Your running at Half Power! I wouldn't do it. Take a look at E-Bay, Plenty of them there or Amazon

The mA tells you the power handling capacity of the power supply. The keyboard needs a minimum of 1 amp. You can use an adapter higher, but not lower. It might work initially, but it will probably overheat - not good.
