Wow, has it been this long. My Technics SL 1600 turntable. Purchased late 70's or early 80's. I may yet have the receipt along with the original box. All the important functions work well. It works well enough to the point of being hard pressed to replace it.
Oldest piece of gear you own
I will start - Pass Aleph Ono, vintage about 1997 or so, followed closely by an LP12, ca 1998. Speakers and tuner both are from 2000. Newest gear is a cd spinner, Simaudio, ca 2011.
