Power Supply of Technics turntables

Hi all,

I used to live in Canada and own an SL-MA1 which I haven't used in some time. I live abroad and will be moving to the Netherlands where I was hoping to resurrect my vinyl system and bring my 'table with me. Initially I assumed that it would have a universal power supply and then I remembered that the frequency of AC supply will be 50Hz instead of 60Hz, which would still throw off the speed of the unit. I don't have access to the unit at the moment, otherwise I'd check it myself, but the tech specs in the manual state 120V/60Hz power which means I'm probably outta luck.

If anyone happens to know if the turntable will accept both 50Hz and 60Hz (and/or 200-240V), it would be a huge help. Thanks!

Look on the power supply. Most are marked with what the input voltage and cycles are supposed to be. If it can take a range of voltage that will be shown there.
 
I think you have a problem to solve. A/C synchronous motors rely on the frequency as you know. if you are staying I would sell and re-buy. If coming back box it up and store it.
 
It's a low voltage DC motor and circuitry. I don't know what it is but probably something like 10 to 15 volts. The 50 or 60hz should be a non issue as it will be rectified immediately after the transformer. Using a step down transformer for 220 to 110 should be all you need to do.

And...

Note that it is a quartz locked direct drive, not likely to be effected by AC mains frequency.

There appears to be several versions of this turntable with respect to AC mains power supply.

In any event, if it is not a voltage selectable unit, then a simple step down transformer of the correct rating should work okay.

Thanks for this. It is the Canadian version, so no selectable voltage switch on it. But that's good news, as I love the 'table and would much rather take it with me than sell it and buy something new locally.
