How long ago did you catch the bug?

My first inkling was about 1972 when a friend mentioned such things as Dual, Thorens, AR, Scott, etc. By '74-'75 I knew about all the Japanese manufacturers (courtesy of a military PX catalog) and about McIntosh. By '76 ​​was using a hand me down all in one Panasonic compact system. The compact system did not last long and very shortly after, '77, came a "proper" 1970's system with such names as Pioneer, Kenwood, Shure, AR, Teac.
