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

A mid 70's Technics SL-1300 automatic turntable. I am just to lazy. I also have an early 1980's Technics SL-10 Linear Tracking Automatic turntable with Technics 310 MC cartridge. A truly unique device.

Tho I don't use them at present, a first generation Koetsu and a battery powered, perhaps the grandaddy of battery powered phono step up devices, Marcof PPA-1.

Luxman L-5 integrated (1975?). It's the first piece of audiophile quality equipment I ever purchased. Built many a great system around it - always flawless. Then marriage, work, moving, kids and 15+ years boxed up in the garage. Now I use it to power my rear speakers in an all audio stereo first quad capable setup.

Works every day and sounds good. Still, I kind of wish it would die so I can justify buying something new. On second thought, in this economy, let it play, let it play, let it play :)

Oldest pieces are a match set of mono block tube amps built in feb 1963. Have upgraded them over the last 8 years. Next is a 1986 AI modulus 2a. Newest item, a 2003 Philips 963 bought for $25 and repair/modded. Had an old fisher system turner/pre with a el84 amp years ago, along came a dynakit system in the early 70's.
