For replacing the original transformer of the CTC5, I wind another transformer slightly greater, with the same mold of the iron sheets, but with more layer, given that the space inside the external iron box is slightly greater than the space filled with the old transformer. I want rewind the transformer with the normal 115V primary, because for me the voltage is not a problem, but with more iron, the transformer will work better with the 50Hz frequency. A friend of mine that has got another CTC5, has confirmed to me that my calculation was correct and the transformer must give 350+350Volts at the plates of the two 5U4GB.
