U67 transformer question

[PhilGood]

Does anyone know the ratio of the transformer in a U67 or a place to buy a suitable replacement? I am working on building a copy for myself. I have all the other parts and a full layout, but no clue what to use as a suitable transforemer.

Any help, mucho appreciado!!

I´m modding a chinese one to be similiar to an U-67
using CM-2480 so I guess that could do.

Maybe it's just because the K was capitalized.

I tried again...

Try his board on PSW.

I just heard from him. He didn't say what the ratio is, but suggested I can get one from Oliver Archut.

It's probably gonna be expensive. I'll have to save up a bit.

OHG!!!!!! I forgot Phil...Damn I dont know what I was thinking...my friend peter drefahl can get you one I bet!!!

I will call him for you. PM me with exactly what you need, and I will see what he has to say. He has my AKG426b and 422, so I need to visit anyhow.

I called Drefahl for you, Phil..he is going to get back to me.

you are going to build one with all of the circuit being copied?

That is not a "Standard" transformer it looks to have feedback windings if you look close. Two of the four windings are used for the output and the other two.....

Good luck

Do you have a real 67 capsule?

Oliver makes a copy with the feedback tap. I am getting either a KK67 or 87 capsule. From what I understand, they're not too disimilar.

Teddy, thanks for the contact. I will PM you.
