I was lucky in that when I grew up in the 'fifties and 'sixties my Dad had an AR turntable (and Dynaco system) given to him by a parishioner of his who was transferred to England and decided not to take his stereo with him. Never had a changer, never got to stack records. And when I got systems I never bought a changer either. So his records (which I now have) and mine from when I first bought records near the end of the 'sixties are in really good shape, luckily. But yeah, many got trashed on those changers.
