I see second hand ones over here in Sweden quite often, where Tandbergs are 10 a penny (there was one in every school classroom once upon a time).
Good place to look is
Tradera
I also have 4 players (5B, 74, 74B, 64), and I was thinking about using the guts of the 64 for a Phono preamp. So potentially will have a spare motor from that? (Or is that project sacrilege?)
