While in high school, I sold "hifi" gear at a local electronics store - Pioneer, Marantz, Sansui, HK receivers, McIntosh, Citation, Bose 901's, Advent, KLH, AR 3a/LST, etc. as well as Henry Kloss' first projection Advent TV's. I could even align one myself, which was a real pain!
With the generous salesman comp discounts (40-60%), I spent all my meager earnings on gear and parlayed it into a Mac 275, Citation 16, Mac pre, Soundcraftsman EQ, Bose 901's, and later double Large Advents to replace them. It was all WAY overkill in a small college dorm room. During college, I worked in a couple of local shops and moved on to a Paragon 12a, Phase Linear 400, Dahlquist DQ10's, among other goodies up the chain from there. Not much food and beer money left, but it was big fun. The vinyl collection mushroomed too, but was unfortunately later devastated in a nasty basement flood.
