"A review of vintage stereo components, mostly made in America from the early 1960's to the 1970's. Many quality component systems were made in American during that era, and many of them still offer outstanding listening quality and are of very high value even today. Altec Lansing & J B Lansing made some very impressive sound systems from the 1940's up for industry, and the home."
