You've explained it rather better than I did, but that is what I was getting at.

I would expect that the voltages would 'track' each other. In other words if one was half of what it should be then all outputs from the transformer would be half of what they should be. As you said, that is determined by the turns ratio of the transformer.

The rectifier heater voltage was half of what you would expect. And yet the high voltage to the rectifier anodes was not half of what the trader sheet said.

What meter is the OP using? Can we trust it?
