Oldest piece of gear you own

My Phase Linear Series II gear.

My ARC SP3c preamp. I purchase it used in 1974 thru a classified ad in the New York Times. Of course, when I bought it, it was an SP3a1. I had it upgraded to SP3c in 2003.

OHM Ls from 1978.
Dual 1264 from 1982.
NAD 7020 from mid 80s.

Actually, I made an error- I have a pair of Ohm F's in my garage. Late 70's I think.

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.
