drive motor type

Hi friends!

While checking Linn parts on the website of a Linn dealer in London,
I've come to realize there are two versions of motor:

"50Hz or 60Hz?
For example, if you live in the UK or any other European country, you'll need the 50Hz version. For the USA or Canada, you'll need the 60Hz version."

So, this is my question:
If I want to buy a Valhalla-fitted Linn deck from the UK,
do I need to have the driver motor changed to 60Hz version? I live in the USA.

What about the Valhalla PSU? As it's 110V-220V, it poses no problem in the US, right?

Thanks much for your comment in advance.
