Need Spice model for mains transformer - please

Hello,

I am no expert at spice but I am trying to similate a complex filter circuit for which the phase shift is improtant.

For this, I need a spice component / model for a transformer with primary and 2 secondary or centre tap secondary.

I need to simulate 230V in and 12-0-12 V out with 0.35VA 50/60Hz

I am not clever enough to write my own model so I am hoping to just somewhere get the whole thing.

I use LtSpice at the moment.

Can anyone help me perhaps?

Regards
