Step Transformer for BAT VK150 m can it work

Hi there

I want to buy these BAT amps and can get a good deal in the US, where I am unfortunately not from so I have a voltage problem; I can send them to BAT to change the transformers but that is too expensive. Can a step up transformer work and if so do any of you have recommendations?

Thanks

What is the voltage where you plan on operating the (USA) BAT amps?

Hi Albert

In France, so 220V

Good chance you will get the best performance from the amps if you have BAT change out the transformers....

Stepping up the voltage from 120V to 220V can be done cheaply with a converter. Converters are usually autotransformers. Best way is with a true step up isolation transformer. But a lot more expensive.

Problem is in either case the frequency will end up the same, 50Hz..... If the BAT power transformers are rated for 60Hz only they will mechanically hum louder and run hotter on 50Hz mains and could fail in time.

A re-generator on the other hand will not only change the voltage but the frequency as well..... Cost? For the size you would need probably higher than the cost for BAT to change out the transformers.
