UTM INDUSTRY audio transformers - from Poland - EU

[innercityman]

I tried the UTM 0547 in a tube microphone, beautiful sound!

Good to know when you consider the price. Have you been able to compare with others ?

 

[Tubetec]

Looks like budget reproduction gear like LA-2a ,1176 and Pultec from KlarkTec could have the transformers swapped out for small money , might make a worthwhile upgrade.

Hi IGS ,
great to see the range is expanding fast ,
A question about the UTM 0547 , can it be housed in a mumetal can like the other small mic input transformers ?

Yes, we can do that. We have cans in stock at the moment.

 

[Tubetec]

UTM is the best thing to happen in DIY audio in years , all of a sudden theres a huge range of designs you can try at a relatively small parts costs .

Just wanna thank you all for such a warm welcome. I really appreciate it.
Sorry for the long lead time, we didn't expect such a large number of orders.
This is the batch we will ship tomorrow, hope some of you will be satisfied soon. We'll do our best to ship all transformers asap.
DIY Rules!

I would like to praise not only your product range but also the fact that you are humble and patient enough to come here and reply to member's questions.

Thank you IGS and wish all good to UTM

Just found this transformers and made my order for some tube mics

Thanks for sharing!

After the successful API 553 EQ Clone build with outstanding sound quality I will also try a UA175b ptp clone build and and l Apes PYE Compressor clone with UTMs. Very excited...

gorgous UTM trafos in copper cover
I am waiting almost ages for other parts (like germanium app14ge from PPA) for my project so i didn't test it yet but my measurments looks promising - very good tolerance and nice build

 

[Murdock]

Hey IGS, congrats on the start of your new business! Looks very promising!

I have a question concerning the UTM3590.
How much current can it take?
And the inductace measurements seem to be wrong. They indicate an impedace ratio of 10:1 which seems not to fit to the published ratios. Or do I have my math wrong?

Sorry if these questions already have been answered.

We are waiting for the permalloy housings right now. They should arrive at the beginning of 2022.
After that, we'll be able to do these kinds of transformers too.

Hi igor, do you know, when these will be available?

 

[Ricardus]

Hi igor, do you know, when these will be available?

Last I checked with Igor those housings had arrived, but they weren't up to his specs so he has to wait for more housings.

Yes i've been able to compare it with several other transformers.. My taste with transformers leans more on the colored/non transparency, so bear that in mind So I'd say that UTM's transformer sounds very clean and transparent. I was super pleasantly surprised when i listened to it, i'm sure its transparency could please a lot of you guys!

Nice!

Which UTMs will you use in the PYE? I’ve been putting off ordering the Cinemag and Edcors for that build for too long, and this might be a good opportunity to give UTM a try!

Hi, I will try for Abe's Pie/Pye Compressor the:

-3515 as Output TX 15K/600 5:1

-2571 Line Input / high Impedance TX / High Ni Content as Input T1 in 10K/10k 1:1 configuration (5K+5k Serial : 5K+5K Serial)

-2546 Interstage as T4 Sidechain Stepup in reversed 600/10K 1:4 (secondary 1k2+1K2 parallel : primary 5K+5K serial)

They should "theoretically" work without any Problems according to the datasheets.... I expect the same cleaness, open behaivoir and transparency from TXs like known in the original Pyes. So I think these UTM TXs could sound the same in this Pye circuit like Lundahls or Jensens would do...my opinion

When looking at the #3510 or #3515, what does "clamped" mean? Are these two transformers gapped and if so, how much DC can they handle? If anyone knows, thanks!

This is a clamp and a clamped transformer. 3510 and 3515 are ungapped.

 

[toolshedamps]

Ahh, thank you for the clarification. In the U.S. we call these "channel-frames". So, no DC on these transformers, we refer to ungapped transformers as "Parafeed". Thanks so much, I'll be placing an order on your website.

 

[LevinGuitar]

Just recieved my order, can't wait to use them, thank you very much!!

 

[TillM]

do you have any plans for a 2622 input transformer, cause I can't order any from Andrey anymore.
