who is first to think of applying for a patent.I can not BELEIVE some of the ancient circuits in common use that some enterprising person decides to make their own such as this one www.freepatentsonline.com/5434921.htmlseems to me not only did I have that in my Apt Holman Preamplifier back in the eighties but also built an almost identical device from an article in Popular electronics around the same time yet the application for patent is a MUCH later date.
