hello i found an old hifi tranformer from amp.....the name of trans is AM-TS-780 NTK......i don't find something in web for this product....so i need your helps....the tranformer have 3 wires from one side and 4 wires from other side...the 3 wires is 1) black 2) 114 volt 3) 220 volt.....but the other wires i don't know...are 2 blue wires and 2 red........if i learn what are the wires, maybe make something from this tranformer......help me!!! :)
 
I don't know if i should tell you this - please don't kill yourself!
A foto would help, together with your measured resistances between all the wires (between red-114v, black-220v, between the two blue wires, the two red wires, both pairs of blue-red wires). The ratio of the resistance of black-220v : black-114v should be 2:1, roughly. The ratio of resistances in : out should lead you to a good estimation of output voltages you have to suspect.
Then I would connect the black wire and 220V to mains (here in europe!) and measure the output voltages on the other side.
HTH, and don't grill yourself or others,
yai.
