I've searched online with not much help. The only info I have is the model "MT-65" and the output (or is it input?) of DC 7.5V. Could I just buy an AC adapter not specific to the MT-65? In the instructions it said that you should use an adapter with the same voltage rating as your power supply. I'm just using a wall outlet, so what would that be? I don't know anything about electrical stuff so any help would be nice. Thanks guys.
