easy xfmr bal/unbal question

Whats the advantage of using only one of the primary/secondary windings, instead of connect them in parallel?

Changes DC resistance and inductance. Depends on what you are driving the transformer with.....

Good point though.

Good point though.

so, both options are good, depending on the application?

Yes, and we don't know your application in this case.

Connecting two identical windings in parallels doesn't significantly change the inductance, because they are almost 100% coupled. But it changes the primary-to-secondary coupling, always in a beneficial way, increases the parasitic capacitance (generally in a negligible way) and halves the equivalent DCR, which is generally a good thing too.
I don't see any reason not to do it.

some great info from both rodabod and abbey road d enfer here 

thank you very much for the help
