I am likely making my move to Hong Kong permanent and I will need to bring my Stereo over from Canada.
So looking for an appropriate voltage transformer for my amp and turntable.
The OTO is rated as 100 Watts maximum power consumption and the turntable is rated at 3.3 Va.
My concern with the turntable is that it is made strictly for 50hz and can't be changed to 60hz (for any reasonable sum according to Audio Note).
I've read some poor transformers will eventually fry gear after several months but I'd have to think there are some good ones out there - These are the only two units that would be used on the transformer.
The other issue is getting something that is quiet and doesn't suck the life out of the sound.
I am looking at (linked below) as it looks to be overkill but apparently more is better with these things.

Most AN equipment at that level does. Better yet, buy one of the new OTOs with dual C core opts.
Observe, don't think
I am checking into that - thanks - Apparently it takes a couple of minutes to make the switch so...
My Dual TT is 50Hz running on 60Hz. I found that setting the speed adjustment fully CCW makes it play in tune.
I could change the idler wheel, but have not done so.
Just changing the voltage as step up / step down voltage regulators do does not address the problem. Unfortunately, “frequency converters” are far more costly than travel adapters, one to two thousand or more. A couple companies to start you out are TEMCo Frequency Converters 800-613-2290 and Visicomm Industries 866-221-3131
Years ago VPI made a small PLC unit where the exact frequency output was adjustable; designed for their turntables although it should work with other gear but it was very power limited. Something like 20 watts maximum output at any frequency. If that's enough for your turntable you might look for one on the used market? Value is around $150 to $200 I believe.
You said Canada to Hong Kong right? Hong Kong is 50Hz 220Volts / not 60Hz. If the AudioNote is already set at 50Hz then all you would need for Hong Kong is a voltage converter not a frequency converter or was that a misprint? I know Canada is a mix of both 50Hz and 60Hz depending on location.
Thanks for the information - this was very helpful. I didn't realize the transformers would not change frequency so the turntable is in big trouble. It is 60hz 120v in Canada but HK is 220v and 50hz.
The frequency converters are much too costly and VPI gets somewhat mixed reviews from what I have read - the SDS is liked but it too retails for $1200. I could probably sell the TT2 and buy a second hand one in HK for roughly the same difference.
Some turntables adapt to the different frequency by changing the diameter of the pulley on the motor shaft. I don't know if this is the case with the VPI, but if so this might be an inexpensive change.
There is also a "VPI turntable power line conditioner". That might do the trick. (This has a variable oscillator to allow multiple speeds and speed adjustment.)

It is the turntable's motor that uses the 60Hz AC to maintain its speed. Have you researched a 50Hz motor from the turntable manufacturer? A motor swap should be simple.
