Alain - My apologies! After looking at the spec sheet, this does sound like a promising prospect after all. It looks like I need to get the voltage down to 10V or thereabouts to input into this chip. Is that correct? I tried searching for LM331 to see if any others have used this but could not find any reference to it. I even tried the Google search, too. Can you recommend a good way to get my incoming AC down to a level acceptable for input into this chip?

Thanks!
