What DC adapter does this clock use?
P.S. I'm sorry that the photos are sideways, the camera I used auto-flips images that are taken at an angle, and that was the only way that I could take the pictures without the flash coming back and glaring in the lens.
UPDATE! I found a really old variable voltage adapter, but it has a fixed amount of amperage: 300mA. In any case, today I'll open the clock and check the polarity. From there, it'll probably be smooth sailing. Thanks to everyone who responded to my post!
But this question is still open to people who have this clock who can tell me exactly what the specs are.
