Your oldest gear?

I had the same complete system for 20+ years.  My current system was all put together over the past 5 years.  But I'm listening to my Ipod Classic in a Bose Docking Station as I type this.  Amazingly, the Ipod is still working, and holding a charge, after +/- 16 years.  But the oldest things would be several LPs that I bought 45+ years ago and still play.  Cheers,

My current main system is about 5 years old (last upgrade cycle, all the same age). My oldest piece...is a 1972 Marantz 1040 integrated amp... I just keep it for nostalgia... my first piece of high end equipment.  

What’s the oldest piece of equipment in your system? 
 

What piece of equipment have you owned the longest? 
 

my ears

Speakers. Dali Mentor 6 purchased in 2012 if I remember correctly. I started to replace them last year with smaller lighter speakers but ended up keeping them and buying a pair of Dali Menuet SEs which was the start of my office system. 

Grace F9L ca 1974.

Paragon System "E" preamp ca. 1978.

Audio Research  SP-6B (phono section) ca. 1979.

All have been active recently or are in use today.

I don't throw much out.
