Never knew Silver and Harman Kardon were related. This is from an audio calender out of Audio Scene Canada 1981, the rest is normal stereo equipment but this Silver is pretty nice looking!
The only stores on here I had been to were Big Wheel and Zayre's, both were big stores with a ton of crappy stuff, they were fun to walk around but most of the products were low-end. I don't remember any of the boomboxes or Walkmans, ours would have had equipment like Lennox, Emerson, Symphonic, Yorx, etc.....
This is interesting, Sony is dropping the "Superscope" Branding in 1975. Superscope had Sony Tape Distribution Rights until 1979 Oklahoma Retailer 1975
