Your oldest gear?

1985 era Carver.  (2) TFM 35 amps, 200 wpc, a Carver preamp with hologram, and a tube CD.  It's my office stereo and frankly it rocks better than more expensive Rotel-Foca-B/W living room stereo

The Dynaudio Audience 42 and 122C I use for surround and center channels will be 25 years old next year.

Luxman PD300 vacuum table with Zeta tone arm

Bought in 1983

Oldest piece i have would be a Yamaha P-350 turntable I bought when i was 14 (1977). So it’s at least 48 years old and I bought it new. Nothing high end about it, but it is my history, nostalgia kept it in a box in the cellar for 35 years. Even more important, it got me back into HiFi when my 14 year old daughter asked me "what’s a record?". Dug it out, refreshed it a bit and been going/operational since (but does now play second fiddle to a newly acquired Sony PS-X50 TT).

Thanks kid.
