Original Nintendo arcade game power transformer (Part number PT-881B) and related items. This unit is tested and works fine. Note that the power switch is missing and was bypassed (wires are tied with wire nuts). You will need to install a new switch if you want to power it on and off using a switch. Unit does work with out the switch, it is just always "on" when plugged in.
We believe it was originally used in some Nintendo cocktail arcade games and the Vs. / UniSystem games, but should work with other Nintendo games from the early 1980s.
