The longest you have owned any gear?

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.

Sorry. I can see that some people still buy Studers on ebay, for about $4k, but don't buy them for over $5k. I don't get it. When it comes to Studer and considering that $4k is already no pocket change, I would be prepared to pay extra $1k if I saw a good reason.
