Most of my audio setup is fine Radio Shack equipment from the late 1970s. Still works, but doesn't get used much these days.
A lot of my still-working music gear (keyboards etc.) is late-1980s vintage, cheap at the time and not worth much now.
I'm a huge fan of Sony MD technology from the late 90s-early 00s. Best physical (as opposed to digital) music storage ever, and the little portable players run for ages on a single AA battery. Best of all, they'll record via analog cable straight from a stereo, you don't need a damn computer getting in the way.
