I assume the keyboard you are referring to is a musical the ivories and not a computer keyboard and the DC 9V is the power supply for it.



With those assumptions, though you enjoy the correct voltage, DC 9V you may not have the right polarity. Look at the baby grand connector, verify the polarities of the inner and outer connector.



For example, the 9V adaptor, on the back of it, it should hold a + and - these are then shown as the inner connector or the outer connector, produce sure this is the same dummy on your keyboard. If you hold doubts, take the the ivories and adaper to your local radio shack.
