I was 27 years old in 1970. I had always listened to AM rock and roll stations and 8-Track in my 69 Chevy Malibu. One could hear the Beatles on AM radio. One night I tuned into the local Philadelphia FM “head” station and the Band was playing “The Night They Drove Old Dixie Down”. I was hooked. I spent the next year and ½ reading Stereo Review, Audio magazine and a Radio Shack manual explaining (i) the concept of how inaudible harmonics enriched the sound of audible music, and (ii) how tape recording worked. In 1971 I walked into a local hi-fi store and walked out with a Kenwood Receiver (20 watts RMS per side), a Dual 1215 turntable with a cartridge (I don’t remember the brand) complete with little RCA cables, a pair of KLH 17 speakers and zip cords for speaker cables, all for $500 total. My first two records were Cat Stevens’ “Teaser and the Fire Cat” and “Tea for the Tillerman”. I was blown away.
