man... really... I think you should just buy one. You don't or didn't say really what you want, nor what you know about smps's... and I don't think you used search even one time... there are several how made thread and build it, just find it... asking like this will get you no where

...for what amplifier you want to use that???

You need an 350W Switch mode Power Supply, in my opinion a "classical" Power Supply is better for sound quality.
Buy an 400VA Torodial Transformator, 8 Ultra Fast Diodes (like MUR860), 2 or 4 10.000µF/50V Electrolytic Capacitors and a few resitors and 0.1µF MKP Foil Caps...that´s all you need and what will work properly for "Music".
Then you have a good "unregulated" Power Supply.

P.S. regulated or SMPS have high frequent switch impulses or or hardly feedback which sound all not very "audiophile" in my ears.
Other people can have other opinions...

"musical" greetings Uli

OK, with you I agree, but .. a toroidal transformer of 400VA with 2x24ac second hand from here costs about 45Eur!? and capacitors 4x4700uF/50V costs 10Eur, Greats (B1) and costing to 1.5 EUR, e.t.c,....means cost power supply a total of about 65EUR!
A SMPS (350W) costs about 30Eur!
People wonder where the math??:
Economy,... economy ...!!?
thanks and cheers!

Radio, I remember you saying you already had a well regulated 35-0-35 supply? Why do you want another one when you haven't used that one yet?

If you want people to help you, you have to help yourself. Search the forum, and ask questions like "I found this project or that project. I have these requirements. Which would be better?". Do a little work yourself, and people will be much more willing to help you. Otherwise you will just annoy them, and you will never get anywhere.

...oh my god, 35€ more for much better sound quality, is ain´t much money. If you want to save money you should bring it to the bank.
If you are listening to music with your heart and soul (like me) you are not able to make such compromises. Economy ??? What´s That???
F..k the EU, I say.

...last words:
SMPS Supply sounds like someone´s sawing at your ears....

Hi uliguitar!
In countries with a lower standard 35Eur means a lot!!!

Hi,
well...that´s a reason for me. I didn´t realize that you are from Macedonia.
Well, then you´ve got to try a SMPS Power Supply. The EU will thank you.
For better understanding: I´m listening music with two "100W Class A"
Transistor Amps...35kg each, 250W power consumption each.
With my "Fun Speakers" (90dB/1W) I use a EL34 Push Pull Tube Amplifier(25kG),
wired in Triode Modus...max. 2x20W Output...power consumption about 220W.
The Sound, in both setups, is fantastic ---> but: the EU will hate me for that.
So that´s what I mean with "No Compromises".
Because I´m working for SIEMENS AG in Germany my pay is not bad, that I can afford it.

best regards Uli

Uli I suggest you should read the rules specifically rule 4 and note 3

This is in reference to post #6 just a friendly warning.

Hi,
I have to say sorry for that, but I just typed in 2 letters.
The rest is in your fantasy... (joke), but I will appreciate that.

>>> I just wanted to say that "the EU law´s" are going to kill all the fun
in the world. No bulbs bigger than 100W(although the light ist beautiful)
no tube amplifiers...because they are wasting energy, no cigarettes in
bar-rooms etc. <<<

worried greetings... Uli
