hvy:
The earlier TD145 had auto stop, but I don't recall it lifting.
There was a TD147 in the shops around the time the TD146 was new, but other than a different arm I don't know the difference.
I heard the TD146 in the early 80's (I think) when visiting my folks in Iowa and saw the new TD147 when I got back to LA.
I still had 2 TD160/Sme combos that cost very little so didn't go for it.
Also, as mentioned, auto stop didn't interest me back then.deKay
