AC Power adapter
October 26, 2019 - 1:13am

Hi all,

The AC power adapter of my piano broke, it is an old Yamaha piano so I'm having a hard time finding a replacement. I really don't know much about electronics so please bear with me.

This is what reads on the back of the original adapter:

Input AC 120V 60Hz 13W

Output DC 10V 700mA

I've been looking for universal adapters but I cannot really find anything of 10V, or even the 700mA, I've found a lot of universal adapters but you can only adjust from 9V to 12V and they are typically on the 1200mA range. 

Would I be ok to buy one of those universal adapters? I welcome any suggestions.

Thanks very much in advance.

10V adapters are rare to find

Hi Andres, 

It will be hard to find a 10V adapter since it is not a standard voltage. Check with the device manufacturer if other voltage levels can be used. Normally pianos will not be very voltage sensitive. So you can buy that universal adapter set it to 9V and try powring your piano, it should work

And for the current rating, your minimum required current is 700mA. You can use any adapter that says more than 700mA so 1200mA is also a good fit
