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?
My oldest gear, but not currently in use, is a 1975 Nakamichi 350 tape deck (purchased along with my SAE preamp/amp, and ESS speakers). My oldest, that is still in my system, are my 1989 Mirage M1 speakers.
Albert those speakers are that old and still sound that good! No wonder you kept them.
I have a McIntosh MI 3 that was made in the early 1960s. It is called a Maximum Performance Indicator. It has a small oscilloscope built into the front panel. You would connect this unit to a MacIntosh tuner (although I believe that you could use it with other tuners as well). The oscilloscope would show the amount of multipath present in the signal so you could rotate your antenna (many people who owned this unit had a motorized antenna that could go up and down and around) and optimize the antenna's position for minimum multipath distortion. It's pretty cool to see the 'scope present the signal.

Scully record lathe with Westerex 3D cutterhead. The lathe dates from 1947.


Ampex 351 tape machine from 1957 (1/2" tape). Rebuilt of course. Unstoppable.

Both sound fabulous.
