I agree. Put an air gap in the main flux path and you can put all the dc through the transformer the wire will allow. But I didn't say a regular old transformer couldn't tolerate DC, Tim, I said such would affect the AC performance parameters.

No matter how you slice it, saving a penny by omitting the reverse biased diode across the LED is poor engineering. It may not degrade performance much practically speaking, but why let it occur in the first place if the solution is so simple?
