Determine that there is any voltage on the primary of the transformer with rectifier remove and dim bulb tester or not, and then start measuring the secondaries, which will be much lower than nominal if you have a bulb in the line. Put a 2 qmp fuse in the line either side of the primary and leave it there. No smoke, the filaments should start to get warm if you change to a 100 watt bulb. No go if the bulb looks as if it is as bright as it is in the kitchen.
