Which Toroidal Transformer To Use

[cabrerachaparro]

Hello,
I would like to start building a DIY preamp and I would like to use this module I found that uses LME49720NA. But I am not sure what toroidal transformer to use for this.

Please, could you give an idea on this?

Thanks

Depends mainly on the voltages required. Not sure what your selected module requires.

Also you have to decide whether you want power supply regulation.
A regulated supply will require higher transformer secondary voltage.

This what it says in the description
Supply voltage: AC12VX2 to AC20VX2 Wide range

Sorry, I should include this in the main post.

Sounds like there is everything on the board except the power transformer,
so I'd go for the middle of the suggested range, 2 x 15VAC.

Is there a suggested VA rating for the transformer? Probably very low.
