Well, first transformer mystery is solved, with a red face. The voltage selector switch (which I knew about, but which is tucked away out of sight under what I think is an add on multiplex adaptor) was switched back to 120V! I know I checked it before applying any power. My cleaning must have moved it back. Thank goodness for the limiter. I hope I've not fried anything. That explains why the symptom was there without the rectifier valve.

So, back to the question of the two heaters.
