trouble with power adapter. I have casio ctk2100

We had this problem laast year when we lost our power cord in a move. You will need to know how many volts go in to your keyboard. It would have been on the back of the adapter it should have come with but alternatively it may be written in the instruction manual or on the back of the keyboard where it plugs in. You also need to know the shape of the plug that goes in so take the one you are using with you to the shops. They are fairly universal items, you will find them in electrical stores, places that sell lots of tvs and computers.... I would guess that the one you are having problems with has A volt out that is slightly too low... You can buy some that are adjustable to the amp out. To be really sure you only head to the shops once take the keyboard with you

Usually the technical manuals for different devices can be found on the internet. I usually search on Google the name of a device and the word "manual" along with it. Either the producer's site or another site has it for free download.

For your CTK2100 you can see and save your manual from Casio's page - it says here, on page 7, that the AD-5 AC adaptor for this keyboard (DC 9V) does not come in the box and you need to buy it separately.

Great job, Andrea! Karma to you!
I am in need for new adapters very often and the best place for me to buy them is Radio Shack.
