500W Toroidal Step Down Transformer

This is a high efficiency transformer.

Power Consumption less than 3w when unloaded.
You can keep it on all the time without worrying about it being hot or even warm.

$150.

Good to be used for 120v USA CD/Turntable/Preamp and small power amps.

Your precious tube life might be 20% - 50% shortened. Singapore PUB voltage might be sometime 10% higher than the rated voltage of 230v, and your amp will be suffered by 15% over voltage and tube life can be 20% shortened.
If you are using a 230/110v step down transformer for Japanese version 100v tube amp, the output voltage could be 20%-30% higher than the rated volte and your tube life will be 50% shorter than the factory rated life.
This Automatic Voltage Regulator is the savior of your tubesĄŻ life!

Automatic Voltage Regulator is a toroidal transformer that can automatically adjust its primary coils to make output voltage constant.

If you want a step down transformer output stable voltage when the PUB power voltage changes or your amplifier load changes, the Automatic Voltage Regulator is your best choice.

Most normal step down transformers output voltage is 10% higher than its rated output voltage when unloaded or lightly loaded, and may cause your amp to overheat or reduce its life span.

Power rating: 1000w
Input voltage 165 - 240v

Outputvoltages:
1) 100v
2) 220v

output voltage variance:
+- 2%


Country of Origin:

Made in Japan.


Price: $300

It is not a good idea to use a 110V output transfomer on a Japanese Amp design for 100V. When lighted loaded, the transformer could ouptut voltage up to 130V and cause overheat and shorten your amp's life.

This transformer is the solution to the prolem. Since the input voltage is rated 240V instead of 230V, when unloaded, the output voltage is 105v and then half loaed, the output voltage is 100V, just nice (Transfermers for amps are usually oversized and only half loaded to get more stable output).

Sanyo Step Down Transformer - Made in Japan Brand New Condition!

Output 100V

Two Japanese Standard 2-Blade outlets, One Earth Binding Post.
Works great for Japanese Power code with Earth wire and spade.

Build-in themo overload protection.

1100VA

Works great for Japanese Power Amps.

Nowadays it is very difficult to find a transformer made in Japan.

In Ebay shop it is sold for $411

Now I sell for $320
