What's the oldest piece of gear in your system?


This site is here for the buying and selling of Audio equipment. This causes me to wonder if most of us have relatively new equipment. If most of it is new, what is the oldest piece of equipment still in use, and why are you still using it?

My oldest piece is a Sota Star Sapphire, but it has been upgraded. It was originally purchased as a Sapphire in the 80's, but was upgraded to a Star Sapphire about two or three years ago.

What's your story?

Mcintosh MR-71 tuner, circa 1966. This is a magical piece of audio equipment.
The question for me is 'What is the Newest?' - which would be a Blue Point Special Cartridge followed by Rega Planar 3, then everything is equally old: ARC-70-C3 amp, modified dyna PAS-3 preamp & Fulton FMI 100 speakers. Oh, almost forgot my TDK CD recorder.
like several other posters mine is a Kenwood KT-917 tuner, which I rarely use due to LOUSY radio in Miami and not a great antenna. It's also one of my all time 'deals' as I purchased a demo for $179 and they're selling used for $600-$800 now
