Step down transformers for Japanese Stereo Equipment


Recommended Posts

I am looking to get an Integrated Stereo Amplifier from Japan. As you know they are of 110v. Is it ok to use this in Australia with a step down transformer?

I see that a transformer price is about $150. Would they be the right price for a reliable unit. Some advice from those with experience please.

Tortech in Sydney make good step down transformers, they can also advise you on what model will be suitable for your situation.

 

Voltage in Japan is 100v

Whatever you do please don't use an AU to US stepdown transformer on Japanese units. US ones are specified at 110-120v outgoing AC voltage. Japanese mains voltage is specified at 100v.

 

The Tortech 240v to 100v isolated ones with 1010 watts or higher power capacity are the ones to go for.

Another vote for a isolated type. Auto transformers are cheaper however they may damage your 100V unit if they fail (open winding). 1000VA (~Watts) should cover most amps however work off the power consumption on the rear of the unit, if it's 250W-600W then go with 1000VA.

I use the Tortech step downs for my Japanese turntables and phono.

  Highly recommended. 

 

Personally for power amps, I would go with the 1000 or 2000 watt models.

What integrated stereo are you buying from Japan?

Why not get one here from the classifieds, with correct voltage and if you source it locally you can even have a listen to it. 
Postage, import duties, possible damage. 
Then getting a stepdown transformer, put that count towards a desirable rotel amp.

I have friend in Australia who ships a car once every 3 months from Tokyo. Amplifier is not that heavy to carry back home in my luggage. But I am also interested  in a Yamaha ns1000 speaker set. That will definitely come in a car. But from what I see online, these speakers are also the same prices as sold here.

Wow, customs do open the containers for inspections for just exactly what you are planning ie transporting items in the car. As for amplifier in the luggage, you won’t be getting it in one piece as it will be too bulky for carry on luggage. 
As for your initial inquiry looks like you will be requiring something like a tortech step down transformer which will set you back around $500 to properly power you amplifier.  
If you trying to save money you not going about it the most economical way. 
Just a thought

items can be a little expensive however need to keep in mind that all(nearly?) items are check and many refurb'd by skilled technicians, they also offer a warranty.

 

The cheap alternative is to buy on the yahoo auction site akin to ebay. Certainly buyer beware however the Japanese are good at disclosure of issues, only consider items from high volume sellers (tens/hundreds of thousands), don't buy a "local techs" failed repair. Access yahoo via third party like Aleado and others. Most don't ship speakers.

Importmonster http://www.importmonster.com/

does ship speakers in containers. Originally setup for automotive "parts" they will now ship "anything" from yahoo.

$189.90 for a 1010w economy model, and $354.90 for an isolated model.
