Quite a few, but many were duplicates of the same model.
-Dual 1219 (my first "stand alone" TT)
-Thorens TD160 MkI/MkII (not less than 5 total - lost track)
-Philips 212 (1 early on and 2 others received in trade later on)
-Thorens TD124 (people were giving them away in the late 70’s)
-Thorens TD121 ($20 @ an estate sale)
-B&O 4002 ($15 @ an estate sale - gave it to a guy I met @ a local thrift)
-Thorens TD125 Mki
-Thorens TD165
-Thorens TD125 MkII (my current deck)
-Lesa (rim drive from Italy - gift from local phile/still have it)
That’s all I can remember, though I did have a Technics direct drive in 1978 for guests to use, but I don’t recall the model (think it had auto play and maybe return).
I also traded the (2-later) Philips 212’s for one of the TD160’s as they were too prone to footfalls (I lived in a 1929 2-story wood frame building).
Couple of memorable decks that housemates had were a B&O 3000 (sparkly sounding compared to my TD160/SME/Sure V15 MkII combo, but good) and an unattractive Sony 3000 (forget the arm/cartridge) that was really good.
