Welcome aboard!

Most of those shaded-pole motors on turntables were intended for use on different frequency supplies anyway. The manufacturer just shipped them with the appropriate size pulley for the intended market.

I happened to be browsing through some old service booklets for Garrard decks from the early 1950s a few nights ago (the RC75 and RC80 series for anyone familiar with them).

As well as the expected 50 and 60Hz pulleys, Garrard also provided one for 40Hz supplies. So where in the early 1950s was running on 40Hz?
