Your oldest gear?

My Basis Ovation turntable and VPI HW16.5 record cleaning machine, both owned since before 1990.

Early 80's (pre Alpine) Luxman preamp. I run my TT through it. Still sounds fantastic!

1959 Bozaks.

~1968 McIntosh MC2105.

The oldest component in my system is a Crown SX-822, but it doesn't get regular use. My McIntosh MR80 tuner is the oldest component that gets any regular use.

My first entry to the Audiogon forum and it is about how old my equipment remains in service!  I have my Pioneer SA-8500 hooked up a Thorens TD 145 with an Ortofon Super MC10 cartridge.  I also have a Wollensak 4765 cassette deck which needs service.  I also really like my (not as old) Kyocera R661 and DA-610 pieces for both their looks as well as their sound.  I also still use the original Denon receiver, the DRA-600 and the original Pioneer multi-CD, the PD-M6.  Sometimes I still get my Sansui Au-717 out to play.  None of this is elite equipment, but it was all I could afford in my earlier decades and now my hearing no longer validates spending a lot on newer and better stereo equipment.  Still enjoying music as often as I can.
