"Build An Audio Phase Detector," Charles Kitchen, Audio Magazine, January 1978.

I scanned this article some time ago and forgot to post it.
Mr. Kitchen may have meant to use the word "polarity" instead of "phase."

Thomas thank you for posting that!

I'd like to point out to our readers that the first page of the article, on page 34, jumps to page 87 in the pdf due to a special section. I extracted the pages to improve readability.
