    Thumbs up

    Alain! Thanks for the link to the ap note! That looks like what I am trying to achieve. I have ordered the parts for the input side of the circuit as well as a variable transformer (for testing).

    Bill - I found the index listing for the article that you told me about but it is not available for viewing. Is there a way to get a copy of the article from them?

    I will try to put together the circuit from the ap note and let everyone know how it goes and post my results. Keep your fingers crossed!

    Thanks everyone!

    Talking Final Result

    Hello All - As promised, when I came up with a suitable solution, I would post it. Here it is... It works well for my application - I just need a good response between 110 and 125VAC. I used a split-bobbin transformer, bridge-rectified it and put it through a voltage divider (that has a trimmer on it so that you can adjust the output a little). Simple and cheap solution. Get nice values over the range I am interested in (about 1VDC over 15VAC range).

    Enjoy! And thanks!
