I read a lot about these TT-101 turntables being 100v etc. These turntables all have a voltage selector.
Japanese turntables does NOT have voltage selectors, they are 100v.
Regarding TT-101 JP Jones confirmed that a sample with voltage selector is not a common sample.
I can add that export version called JVC, not Victor (which is a Japanese version).
Every 100v turntable can be used with step down (or step up) transformer and it's fine!
