Stereos were once an incredibly important bookshelf-filling music-delivery system. Much time was lavished on discussions of which were the best components, whether it was better to have an all-in-one receiver or a power amp, pre-amp and tuner, which massive speakers to buy (and how many). A true stereo-head preferred to listen through headphones in any case so why bother with those massive JBL’s? Above is a 1978 commercial for a Sansui stereo that stars, I believe, my High School Health Class teacher. As I recall, the textbook for that 1980 class was from 1960 and featured, among other anachronisms, grooming tips that included the proper way to grease your hair. The caption underneath the dorky kid from a ‘Leave It To Beaver’ episode is burned forever in my memory: “Oil on the hairshaft provides attractive sheen and luster!”
