Your oldest gear?

All from the 70s.

Sony Tc-K7II cassette

Pioneer SX-1050 receiver

Pioneer PL-630 turntable

Teac A-2300S open reel

JBL L222 Disco speakers

SAE 5000 Impulse Noise Reduction System

Not in the current mix are a pair of JBL Dorian S12. Bought in the late 60s from Allied Electronics on south Western Avenue in Chicago.

My oldest piece is my Rotel CD 1572. It’s been spinning for 21 years, although these days the Yggdrasil does the DAC work. I was using an Adcom 545 (about 30 years old) as a backup amp but it decided to quit working this weekend, so the Rotel is the oldest.

Dad's Altec Carmels from the early 60's, my Alter VOT A7-8 from the mid 70's.

Empire Troubadour III turntable is slightly older than my modded Thorens TD160.  

Most of my system, especially the analog side, is from the late '80s.  You can look up my virtual system if you want the particulars.  The newer stuff includes my Lyra Kleos cartridge,  Hegel V10 phono preamp, the digital gear and some cables.  Everything else is approaching 40 years old, although the speakers were completely refurbished a few years ago.
