@billstevenson ..."I used the stacking feature at that time, still have all those records."
I had a number of record players that stacked and dropped between the mid- 1950s and 1970. All of them sounded terrible in comparison to even the most basic high end turntable. But, yes, they were convenient.
Well, I’ll be... there are some on the market... as if it is a new idea.
