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
I have a Denon DP-60L w/ Grace F9 cart., Conrad-Johnson PV6 Preamp, Acoustat Twin-120 Power Amp all bought in 1984. I also use a pair of JBL L-100s that I bought in 1975. All this gear was purchased new and is still in use today albeit some repairs and recapping along the way.
I've owned my Basis Ovation turntable for about 24 or 25 years, it continues to serve me (and, of course,the music) well.  Upgraded it once to add the Debut vacuum system, platter and bearing, that's it.  Very well-engineered and well-made piece of equipment. 
No open reel decks, unless I missed it..
I wonder, how many more years can electronics in my Nak682ZX deck last? It was made 36 years ago, all original except capacitors. It is serviced and calibrated every few years.
Still going strong after 30+ years - my Audible Illusions, Modulus 2 pre amp. still in use and sounding great.
Inna, you did miss at least one open reel deck---my Revox A77, bought new in '72 and still in my possession.
