If you are worried about things going bad I would stay away from tube electronics. Tubes always go bad and they can do it in a number of ways.
Question regarding older phono preamp
My phono preamp is by far the oldest piece of gear in my system. It's a 1998 Tokyo Sound PE100 I got off the Gon here about 5 years ago used. My question is do the internals of a solid state phono preamp degrade over time? Everything sounds good to me so no issues. I'm considering "upgrading" to a new unit possibly tube.
Thanks!
