My very first real job ~1977 while still in high school was as a part time salesman at the local Lafayette Radio. I was a kid in a candy store! Was running a $200 Sanyo Integrated system at home for several years prior. Soon I had all Lafayette/Criterion separates: integrated amp, tuner, phono, speakers with HEIL Air Motion Transformer.
Nearby shops sold Magneplanar, McIntosh, Klipsch and other goodies I saw and heard for the first time.
Then on to college where I landed a similar gig at the local Tech Hifi and away we go....
