as you can see, it's 15v 0v 15v center tapped transformer.
I want to make these two transformer behave as a 30 vct transformer. then, in this picture, is A 30V and B 0V(center tap) and C 30V, if you see this as a single transformer? and the current should be same as one of them.
Also the input says' 0v, 110v, 220v'. i have a standard 220v socket, then should i put one cable(two ends) on the 0v and the other on the 220v input?
those two transformers are completely identical.
