Bought my first system in high school in the early 70’s. Went to Tech Hifi in Springfield, NJ and got a low end Sansui receiver, Philips GA-212 turntable with AudioTechnica cartridge. Speakers were EPI 120. Later steam cleaned cookie sheets in a bakery over winter break to make enough money to go back to Tech Hifi and get a Technics cassette deck. First vinyl album bought and played on that system was Derek and the Dominos, Live in Concert.
Around the same time, my Dad got a system for our family room. Also at the same Tech Hifi store, he got a Sansui Seven receiver, Elac Miracord automatic turntable with Audio Technica cartridge and Ohm B speakers.
