[unregulated, audio-grade power supply] Please help

Hi amigos,

I would like to use my Toroidal PSU 24VAC 300W with my TPA3251 (3E Audio AUMT-0140-2-A)


I need a unregulated audio-grade power supply to convert AC > DC

Since I have been living in France, I wonder if I can order this one and if it would fit :

I want to get closer to this project :
