What can these trannies be used for?

[Unips]

I have unsoldered some trannies from and old hybride unit. As you can see they are named LL5007 and ST5146. I have asked Lundahl and they say the LL5007 is a small high impedance line transformer, 1+1 : 1+1; I have no info on the ST5146.



Anyone who can give a tip for what they can be used for? Is it possible to measure some data for them? I have heard that it is not a good idea to measure dc resistance. True?

zero-field input circuits? NTP made some with transformers this small..

Attached NP's version

Thx Jakob! You are right. It was taken from an NTP unit! I must read op on zero-field input circuits. I hoped that I could use them as normal input trafos, but they at too tiny for that, right?

Anyway I can measure the ST5146 in a meaningful way?
