You can get 12v linear power supplies online cheap but they will have EI transformers . I'm in need of a 12v 5A PS with a torroidal or pot-core transformer as well because I need to have the lowest radiation and toroidal and pot-cores emit less radiation , I've looked extensively online but I cant find anywhere that sells PS's with torroidal or pot core transformers.i need a 12v toroidal power supply no more than about 5 amps max, to power my valve preamp. how do i build one or is there somewhere i can buy one ??
Does anyone where you can get one in the US? Or get them built at a reasonable price?

This seller sells a 12v linear PS with torroidal transformer, I bough one and they are very nice but they are actually 4A not 5A so it doesnt work with my device well, still looking for someone that can build me a custom one.

Does the 12V need to be regulated (how tightly)?i need a 12v toroidal power supply no more than about 5 amps max, to power my valve preamp. how do i build one or is there somewhere i can buy one ??
cheers Dom
Why does it need to use a toroidal transformer?
You may want to read this article, especially his comments on toroidal transformers:

I believe it does, I'm not sure how tightly (I'm still somewhat of a newbie at
all this)
Thanks for the articles the main reason I want it to have a torroidal transformer is because of the lower magnetic fields and better power efficiency.
If I had the time I would definitely dedicate time to learn how to build one it doesn't seem to difficult except for maybe the chassis, but unfortunately I won't have time at least until January.

Using a computer-PSU requires modification of the regulation circuit because nearly every of them weights only the 5V-Output or it has at least the highest priority.
No load at 5V will result in a Voltage around 10,5V at 12V output.
(I'm running a carhifi-Amp on a omputer-PSU)
