Spec did you ever cast an eye over this circuit again? I'm not in a hurry to get it up and running, it was just an idea. Perhaps it could be used as a linear post regulator along with some of my / our SMPS circuits.
Sorry Gordon, I was all talk and no trousers on this one. I have looked it over though and have the information in my head. I will post quite soon and describe what I think. A linear post regulator is a good idea.
It is 1:50am. Why aren't you in bed asleep? Me, I can't stop coughing.
