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

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

also

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

Both sound fabulous.

My Dad.

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
tuner: MAC MR-71, Eico HF-90 from 70s and 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

Me, but nothing to do with old or new. :-)
