Your oldest gear?

Only two older pieces for me. An Audiolab 8000S integrated amp made in England and I purchased new in the late 90's. Still works great. I've only cleaned the volume control and switches on it but no longer use it. Also still have my Koss ESP-950 electrostatic headphones I bought sometime in the 90's. They work and sound great and I occasionally still use them. These have been replaced a few times over the years under their LIFETIME warranty!

@willywonka  I tried too get a pair of Koss electrostatic headphones repaired a year or two ago- called the company- they no longer service the headphones. 

I also had a pair of Koss headphones I bought in the 70's- don't quite recall the model number. Unfortunately, I have no idea whatever happened to them. 

The 70's Koss headphones that imparted a splitting headache after a few minutes of wear? I had a pair of those... I think everyone did. Ouch... the top of my head hurts just thinking about them. 

@ghdprentice no- not those. Mine were light open backed and a pleasure to wear 

The Koss head crusher.
 

I think the most affordable, nicest sounding, but most uncomfortable Koss headphones were the 1970’s PRO 4AA’s.
 

As l say, they sounded brilliant, and they completely isolated you from the outside world. Closed cup and heavy, and had outer ear crushing leather pads. It was okay for the first side of a record, but after that your ears started hurting and sweating. When you took them off your outer ears felt as flat as pan cakes.
