Default Re: Don't try this at home...

I love the books from that era. So much dangerous stuff it's unreal. A couple of favourites (sorry I don't have the titles) were proper stinkers. The first involved making your own point contact transistors using a variety of extremely dangerous carciogens and acids. The second was a book on economy valve circuits of which none contained any notable transformers on the mains side of things.
