12782 Lift Bridge Power Supply

It's a 12vAC 3A wall wart. See the photo in the parts list link. I hope you have the controller. This bridge has no known schematics. They have been lost over the years.

Search the forum using the part number and read the interesting threads.

OK thanks!  Just to be 100%, it's a 120VAC to 12VAC, correct?  I also see a bunch available online that are 120VAC to 12VDC, so I want to be certain i get the correct one (we all know what happens when AC is applied to DC electronics).  I do have everything else, the original controller, extension ribbon cable, track switches, etc...  Just the power supply decided to up and leave.
