Item : B00005BMSN Customer Reviews Right adapter. by .. J. Knoke (San Diego) No problems with this adapter. I bought a keyboard, the stand and this adapter all on Amazon, using their recommendations. All works well. Casio Power Adapter by .. D. Kircher (Arlington, TX) I received my father's Casio CA-100 keyboard a few months after he passed away, but the power adapter was missing and it had to be a specific item in order to work. Although the keyboard was at least 18 years old and not sold anymore, I found the adapter on Amazon and now it works beautifully. My dad was very musical and I'm glad to have something of his that he enjoyed and that I can enjoy too. Does what it's suppose to do by .. william (Arizona) While it was a bit expensive for what it is at $15, it does it's job and saves me money on batteries. I can burn through six AAs pretty quickly with my keyboard, so having my keyboard run on AC is a definite win. One note - the adapter pictured shows a straight connector to the keyboard. The adapter I received had a right angle connector and the "power brick" was a bit flatter. Adapter for Casio CTK-700 by .. E. Mockler () I have had this several months.
