Hi,
A quick search didn't turn up anything too interesting...
What's the best thing to do with unused transformer windings, both for audio transformers and for power transformers. My instinct tells me that an unused winding needs to have some sort of load, or else the transformer windings will break down (like a tube gtr amp without speaker load?)
Power example:
Multi tap power toroid with but at least one of the multiple windings will not be used. If the proper approach is to just load the unused windings resistively, is there a good amount of current to draw? 1%, 10%, etc of the max winding current?
Audio example:
Quad filar transformer being driven 1:2 (3 windings used). What to do with the 4th winding? Parallel it with the primary? Load it down?
