[unregulated, audio-grade power supply] Please help

[daniboun]

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 :

Module d'alimentation lineaire double 4x 10000mF 50V - Audiophonics

I want to get closer to this project :

The 24VAC input would give about 33VDC, so it will work.
Your transformer should have two 24VAC secondaries to use this board.
A single 48VAC center tapped secondary winding would also work.

That will work nicely. Compact size, AC in from the transformer and smoothed DC out.

Thanks. But my question was rather about the power supply itself. Since My PSU is a 300VA (300W)
does it inspire you?

The electrolytic capacitors are likely of low quality.
Maybe someone in the EU could suggest an alternative board.

I thought EVOX and Nover capacitors were pretty good... hummm
Thanks )

Normally my single 24Vac should Also Work ?
The secondary of my psu is a single 24v

Most likely will get low quality/fakes capacitors for that price ....buy the board only and populate with your own components.
