We got spoiled, all my 1st Brystons .5 pre, 2BLP & 3B had 5 years..and did come in handy on numerous occasions, repairs also had 2-3 day turn around. lol
Only one that took longer was a 3B NRB I purchased in 1993 that developed a problem 10 years later and went back and forth from service 3 or 4 times until Chris Russell stepped in and replaced it with a 3BST in 2003.

Like many things today, in retrospect we had it good.
But totally understand 10 years, new owners, the industry has dramatically changed, margins have diminished, parts availability, labour costs and very few households actually have a stereo system.
