Step down transformer for a turntable

There are numerous individuals using Japanese TT's with a 100V Step Down used on the Power Supply. 

They will work just fine.

A Variac might also be considered.

When I bought my Denon DP-80 back in the late '70s, it was supplied with a Denon branded step down transformer. It worked fine.

A small decent transformer (nothing big or expensive, just avoid cheap) is all that is needed, no hum, absolutely transparent. (I use Amazon because easy return IF ...)

My only concern is to forget my JVC TT81 is 100 v, and forgetting to put the transformer in line somewhere. My memory sucks.

plugging 100v TT directly to 120v. Anyone know if that just wont work properly, or if serious to avoid as damage likely?

No problem at all.  Oversize the current or power required by 2x is all you need.

On the other hand, if it uses a separate DC power supply you may be better off just buying a local replacement.

Dear @audioag90 :  Like   @cleeds  I own the Denon DP 80 and runs excellent, so go a head with out have any single concern about.

Step down fine. With a high torque DD startup like a DP-75 or 80, i would oversize beyond 2x, but i’m a belt and suspenders kind of guy. 2x is probably good advice.

With the DP series tables it also pays to look under the hood - pull the platter and look for a multi market voltage switch… many of the tables were built this way…i have 1 that came from Italy… the internal  transformer has a lot of voltage pick offs to the switch. In certain markets, as is the case with my New Zealand DP-75, the switch is there but covered by the sheet metal platter bowl. Remove the motor cover to access the switch,

Elliot, yes, plug your 100V step down into 120V AC outlet. That’s why they call it a step down. I’ve got a DP80 and a Kenwood L07D each plugged into its own 100V step down. A 50W 120 to 100 transformer is more than adequate for any TT that needs 100V.

Thank you everyone for your responses.  I am a little confused by the recommendation to “oversize” by “2x”. What are you referring to?  Thanks again.  

P.S. I knew you guys would know.  

Nearly all TT motors draw less than 25W. So selecting a 50W step down gives you 2X headroom. In fact even 25W is high for a TT motor.

@lewm  thank you for that clarification. 

My Japan market Victor QL-A75 runs wonderfully with a step down transformer, it draws 16 watts. Like others have said better to have more watts than needed. Avoid the cheapest ones. The one I use is rated for 1120 watts continuous power, and I plug two devices into it.

Again, thanks to all who responded. Exactly what I needed to know.
