I’m curious about the 72 watt, 4 amp, LionChief wall pack Power supply, 6-81603. The catalog doesn’t specify whether it outputs AC or DC. I guess the assumption would be DC because it uses the LionChief product name. It would be a nice if they spent the extra money printing the two extra letters “DC” to verify the point. I’m not sure but I think it’s the only Lionel Power supply description that doesn’t verify the type of output.
