Your oldest gear?

I have some old gear, but nothing in my main system is more than 3 years old. 

I took a hiatus from audio for a number of years.  When I got back into it, I upgraded everything. 

IIRC my Classe DR3 VHC were made in the late 1980s and the Classe DR7 was from the same period.  Another system uses Martin Logan CLS speakers - same period, as is a Belles A amp

Denon dp-57l, 42 years young.

1985 era Carver.  (2) TFM 35 amps, 200 wpc, a Carver preamp with hologram, and a tube CD.  It's my office stereo and frankly it rocks better than more expensive Rotel-Foca-B/W living room stereo

The Dynaudio Audience 42 and 122C I use for surround and center channels will be 25 years old next year.
