Before you condemn the transformer do a resistance check between the transformers HT winding centre tap tag and chassis, it should measure approx 101 ohms, also measure the resistance across the total HT winding (the other two tags of that winding) and also between the centre tap tag and both of the other two tags of that winding in turn. Power off of course.
