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

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.

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

Both sound fabulous.

Aside from NOS tubes it's the McIntosh MR-73 Tuner, circa 1969.

I'm not sure which piece is older but they're all from the same golden tube era.
Speakers: Jensen CX120, EV 12TRXB coaxials from late 50s
amp: Lafayette KT550, Heathkit SA-2, scott LT-48, pilot 240 from the late 50s early 60s,
preamp: HK Citation I, Eico HF-85, marantz 7c, dynaco pas-3 from the 60s

Turntable: EMT 930ST from the early 70s

The newest equipment I have is Marantz CD 17 MKII from the late 90s

I guess that makes me a "vintage" guy

Happy listening
