I'm not sure I really understand your question or that I am giving a useful answer. A given X-ray transformers is designed to deliver a voltage that is dependent upon the size of the load that the x-ray tube presents. Suppose a transformer is taken from a machine that was designed to deliver 125kV and 300mA across an x-ray tube. Now suppose that you subsitute a tube rated at 125kV and 150mA. Because of the reduced load, the transformer can delivery considerably more than 125kV across the tube. The amount of voltage variation will depend upon the quality of the transformer. With the extra voltage, the penetrating power of the x-rays will be increased, that but temperature of the anode might be much above its rating. When you see 125kV on an x-ray transformer specs plate, it means only that the transformer will deliver 125kV to the particular x-ray tube installed at the factory. And do be careful with these high voltage power supplies. One mistake and your history.
