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

Shure V15 mk IV cartridge - probably '82 or so... Sean? I bought it from our esteemed colleague with 2 new replacement Astatic Stylii not long ago. Lovely retro styling, and the gold plating was even decent, I was very pleased. I have it on a Michell Gyro SE with Rega RB600 arm and Channel Islands pre with outboard ps. About as proud a vinly rig as I could think of assembling for this money, and the sound is killer.

As a bonus, it's always nice to play some LPs and tell the grooving listeners that they're listening to a phono cartridge that's old enough to drink. Play on!

Classe Audio DR6 preamp-early 90s vintage

1972 Thorens TD 125 turntable, but I have to confess I had it fully serviced and rewired a couple of years ago. And the cartridge is pretty new.

Nakamichi 682ZX deck,made in 1979-1981.With TDK reference tapes it's a hell of a sound. Also, Purist Audio original Aqueous interconnects being used with the deck; don't know how old they are.

Luxman T14 FM Tuner. As good as any audiowise, and by far the most beautiful.
