Wow does this thread take me back. My after-school job in the late 70's was as a tech at a high end audio dealer, including Adcom, Nakamichi, McIntosh, etc. Mostly I fixed speakers and changed parts for the guys who knew what they were doing. I re-coned many a JBL pro sound speaker. I ended up an electrical engineer!

Just to keep it bicycling related, I rode a Raleigh Gran Prix, with a bunch of upgraded parts, to work, until I had enough money to buy a full Campy Alan Super Record. I paid 900 bucks for that bike in 1980 and everybody thought I was crazy.
