Review: Great Replacement Power Adapter for Casio AD-1 / Casiotone MT-30 - I needed a power supply for a Casiotone MT-30, which uses a Casio AD-1 power adapter. While the MT-30 is not listed in the description, this cord fits perfectly and works flawlessly. I tried using a "universal" power adapter I had lying around the house. However, even when 7.5V was selected, the universal adapter would produce a buzzing noise from the speaker. With this cord there is no buzzing noise, it sounds just like it's running off the batteries. Great cord, exactly as pictured.
