I can see how a power supply transformer used for step-up to generate high plate voltage might be vulnerable to short. Certainly flyback transformers are vulnerable to that condition, and take out the horizontal output when they do. But I do tend to find the most common failure mode as being opens especially with low voltage power supply transformers that step down to ten or twenty volts.
