Is the Technics SP10R motor controller using a switching power supply

You can always run it off a variac or stepdown transformer.

@pindac 

What plinth do you use with your SP10R?

Can you see the back of your SP10R controller to see the inout voltage requirements please. 

I have FR66s and so am very interested in the Glanz 12". 

I use a Koetsu Coralstone Diamond 

This is copied from the online review linked below ("The external power supply is a switch-mode type, able to work on any mains voltage.").

Of course - confirm it with the manufacturer.

@ddriveman I do not own the SP10 R, it is a friends, this individual was initially a user of a Linn LP 12 that has many Upgrades included.  They purchased the SP10 R after being demonstrated my modified SP10 MkII. 

As for the TA Selection they were suppled a range of TA's to trial with the New un-plinthed  TT, mounting TA's on a Standalone Arm Pod.

I even loaned a SME IV to be trialed with other TA's, the 12" Glanz was the one that made the biggest impression.

This TT, is mounted in a Solid Aluminium Plinth produced by a machine shop to the owners dimensions, the TA remains mounted on a Pod.

My suggestion for you as a Plinth Material is to investigate the use of a Densified Wood such as, 'Panzerholz' or 'Permali'. To attain knowledge of this material early on in your planning will give a good footing for the future plans. I know from personal experience how valuable this Plinth  type is a addition to a DD, especially the Technics SP10 design.

Thanks for your info.

I have a PanzerHoltz plinth for my current SP10mk3. It's an Albert Porter plinth.

I should be able to drop in the SP10R into the plinth.
