Denon DP-60L turntable, several cartridges (Dynavector Ruby, Dynavector Diamond, Ortofon, and a couple more), Sota head amp,
and a G.A.S. Thalia II pre-amp - all purchased
1980 from Paul Heath Audio in Chicago. That makes for about 37 years. I have the original boxes and packing materials for the turntable and pre-amp.
Better yet - A pair of Avid 103 loudspeakers purchased 1977. That makes for 40 years. I have the original boxes somewhere, but the cardboard has gotten so dry and brittle they are almost unusable. The speakers work fine.
