High end transformer manufacturer in Europe/UK?

[45]

This guy in Romania can make very good permaloy transformer and probably much cheaper than the japanese versions:https://www.diyaudio.com/forums/members/dorin-bodea.html

I did not know. They look good indeed. Thanks for posting the link.

Mr. Ogonowski in Poland makes very good transformer:

Ogonowski.eu - profesjonalne transformatry do wzmacniaczy lampowych

Best wishes,

I second Frank. Happy Ogonowski customer as well.

Since I was mentioned here (thanks!) have a look at my (only) current open subject here;

Iron Schmitt, Concertissima & "the third" phase inverters 🙂

You can check my FB page too, (in signature, not too often updated and the web page is temporarily down 🙁 ) where I have some "permalloy" jobs, like volume control 24 steps transformer (not autotransformer!) 1:10, 600Ω-60kΩ, line level input.

@thekid777 - Now, speaking strictly of permalloy 80, today's entry on the above FB page describes 2 step-up transformers for MC cartridge, R2D2 and C3PO, enjoy 🙂

@dvb i did mention your FB page at first, but then delete it as i didn't know you'd like your personal data being here...i saw your 2A3 tr driver recently on your FB page but i didn't follow your work since 2018 when i left that romanian forum...

Thanks but I have nothing to hide, my profile is public.

Best regards

ok ...i didn't know that page...just your profile.

There is this chap - Audioröhrentechnik Ausgangstrafo Übertrager Bandfilter Spulen Röhren Audio Fassungen 516201 516228 516236 516260 516686 NF-Übertrager Drossel Trafo Hifi Highend I've not ordered from him myself but have heard good things.

I have ordered several output and also power transformers from Reinhoefer.
The quality is superb. Maybe not boutique stuff, but the performance is absolutely great. I highly recommend their transformers.

Among the ones I bought are a pair of big M102 output transformers for a KT88 SE amp. They sound and measure great. I also bought smaller ones. Equally good. And the craftsmanship is on a level, Germany was once famous for. It is obvious that someone in that company takes pride in their products.
They sell open and nice looking enclosed versions.
At the moment, they unfortunately do not seem to take orders from individuals as they have a big backlog.
I hope they open again, soon. I need another power transformer.

Cheers,
Martin

PS: No affiliation with that company, although my post sounds like an advertisement.

Thanks again!

50AE: can I contact you directly to speak about it?

And then there are ultra high permeability nanocrystalline toroidal cores which beat the mu of 80% nickel for less cost.

Hi Alexander, can you expand on that? Compare HiB?

Few days ago arrived the first samples of C core nanocrystalline
Tomorrow I will test the interstage
Then a s.e.
If they will run fine will go in production

I look to replace a dedicated LL output for 70mA, about 3k5, to about 8 ohm.

For high permeability applications, such as input transformers or TVC, mu metal or torroidal nanocrystalline toroids built of, for example Vitroperm are the way to go.

Cannot say the same for nanocrystalline C-cores, most of them have mediocre cuts. Usually, a lot of permeability matching of cores happens to be the case. Not suitable for applications with high permeability requirements IMHO.

Starting the test
Not so bad for the start point
