A Hi-Fi Primer Part 1 & 2 - 1956

An early primer on Hi-Fi. I haven't cracked open a modern Hi-Fi magazine in many years. They usually give me a rash. Curiosity may get the best of me because  I'm curious what sort of instructionals they have. Will there be any articles on Hi-Fi? Stereo? Or will it be how to dial in that 66.6 surround sound system.... < /RantOver >
