toroidal transformer

Your opinion is worth anything?
Is he good enough to build a nice power supply 9V to my project on the denon dvd 3910 audio circuit

IF it works .. then why not.
There's not that much in the way of 'Magic Audio' Power Transformers available.. at least not yet.
Assuming that it puts out a Voltage that you ultimately can make use of.

thanks
When I think about it
I do not think that this transformer will not help me
Because I need to voltage the to the dac of
9V+
9 -
This transformer has only one
Secondary.
Sorry for asking i did not paying attention
Sorry :rolleyes:
It seems ideal to me to me
But a bit expensive
25VA Encapsulated Toroidal Transformer 115/230V, 15Vx2

25VA Encapsulated Toroidal Transformer 115 230V 15VX2 | eBay
I'll see if There such like thisFor Sale
In voltage
12V +
12V -
Thanks again to all who respond

If possible ask another small question
How do you determine the value of the fuse to the power supply?

Hi Dazzz
Can you give detail of this toroidal transformer OD,height and wet of the transformer or any details you like to shear. Because I have one toroidal core and want to make my own transformer your information helps me lot.

I've never built a
toroidal transformer
But I'm sure there's a here alot of experts on the subject.

See this guide on YouTube

It will take about 25 turns of wire to make a new secondary with enough voltage for your use. I suggest twisting four wires together then winding those to make four new secondaries. Then use a bridge rectifier on each. Wire two in phase and two anti-phase. The you can combine one of each to give you less line noîse and the raw DC. A simple CR2C filter should then feed your regulator chips.
