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

Albert,

Check out the schematic provide in your link for the transformer. Odd the unfused side of the 120V secondary side of the transformer is not connected to earth ground. The 120V secondary is floating....... Is yours floating?

I'm aware of that, it's typical for Hammond isolation transformer. Look at this link for explanation

I did not use the adaptor as my turntable is a two wire (no separate ground) system.

Off the topic but related, I have no ground on any of my four VTL 750s, they sound better without. I cannot speak for BAT.

IMO isolation transformer is a wrong route. It is fine for stuff that doesn't need a lot of current - DACs, CDPs or the TT you mentioned. Then you can easily get sth with multiple VA rating of your unit.

For a pair of BAT monos, you would need a 4-5kV one, if sound quality is not to be significantly compromised. 5kV transformer is neither cheap, nor silent (you would have to move it into another room).
