The longest you have owned any gear?


Not counting accessories such as a Zerostat which I bought eons ago, the one piece of equipment I own which I've had the longest is my turntable- 19 years now. 

What's been your experience? 
128x128zavato
Polk Model 10A from 1979. They're in my home theater system now. I still use a Burwen Research 1201A for filtering hiss when I dub LP's to disc. A 1977 Army purchase!
Optonica is a name I’ve not heard in quite a while! 

Its nice to go see that some people have gear that provided real long term satisfaction. 
Forgot to mention 18 years old CEC TL5100Z belt drive cd player. Had to change the belt after 3000 hours.

I bought the Ohm Ls currently in my family room in 1978. The Dual 1264 also in there in 1981.
