ff: The Atelier 1 isn't an all-in-one, but a component system - consisting of the P1 table, C1 cassette deck, T1 tuner and A1 integrated amp. You can find a German brochure, also over on Lulabu's archive - there:

So, as already written above, there's no such thing as a 60 Hz pulley for the Atelier series tables - neither for the P1, nor for the other three that followed in the next couple of years...

P.S.: Darn, that reminds me that I still have to revive the PS550 I got from my stepdad (brochure pic over there:
