Where do you get your transformers?

[OliG]

Hello,

I'm looking for a toroidal transformer to power an Aleph 5. I see that the rails should be ~34v. So I guess I need a 25-30v transformer that provide 650-800VA. The question is : where do you guys get yours?

I've looked at digikey, mouser, partconnections and piltron. Piltron do not have stocks in canada, and partexpress offers avel linberg transfos, but none have adequate voltage/wattage...

Thanks,

Oli

I got mine here: Toroidal Transformers for power supplies and isolation in medical, instrument, audio and control panel transformer applications. . they will get you any specification that you need.it will take approximate one week ( made here in the USA). the quality is top notch.I strongly recommend them.

in Canada, you could try this guy:

SumR - Richard Sumner Technology:: Primrose

Thanks for theses suggestions! I already contacted them.

It seem that the most adequate AC voltage for an Aleph 5 is 2v28V, but I did not see any seller that offer this voltage. I guess I will have to go custom, but before, I would like to know if it is possible to get a 2x30V transfo and reduce voltage on rails with a regulator or voltage divider? I already did this using a LM317T regulator but it was a tiny power supply carrying a lot less current than the 1.5A than the lm317 can output.

If im right, with a 2x30V at 800VA, that would be almost 10A per rails... is it possible to get the ~42VDC to the ideal 34V without too much pain (and heat)?

Thanks !

I do not know if Canadian shipping is an issue, but this seller has good transformers and good service.

Antek - AN-8430

No affiliation except as a customer.

Antek does list shipping to Canada:

Antek - Prices

I'm guessing we get hit with duty when we receive it. I'm planning to order from there within the next week or so.

Check Partsconnexion in Burlington Ontario. I saw some on Canuck audio forums for sale as well

Thanks for all the suggestions!

So far, Antek are by far the least expensives transformers, and they seem to carry every possible type. Do they have an ok quality? What can I expect from a transformer almost half price of a piltron?

Thanks !

I can highly recommend the custom wound transformers from sumR, Richard is a great guy to deal with too, fantastic quality stuff. the only thing that stops me using him for every project is the shipping from canada of such heavy packages is insane!!. if I lived in canada try and stop me, I would be ordering them left right and center.

as it is for anything mission critical, I go to him. the fact you can specify pretty much anything is great. for my dac I got 3 fully encapsulated transformers in cans with 18AWG solid core pure copper leads. also being able to order with 240v primaries instead of having to wire them in series was cool, so much neater.

Transformers.

Guys, don't laugh, try Ebay. There are a ton of them on there.

No one mentioned Plitron?

I've bought from Antek before.

Well, they take too long and they need at least a minimum of 5. They are good but. I rather buy from other companies here in the USA.

See all the Canadian flags here?

Minimum of 5? What makes you think that?

hehehehehe no offence here buddy!. Well I needed a transformer for my new project and I went to their site and try to order one....but guess what? They asked me to order a minimum of 5 ( maybe I am wrong here) and they said it will take TWOO WEEKS ( I am right here).
