Neutrik NTE1 NF

It seems to have done the job on a non critical P48V balance to Unbalance PSU with electret directional Omni's (have not used it critically with AKG 414's or Earthworks as I would probably go up market for the best at that point or not use transformers at all...) However, no obvious problem especially at the price and I assume they are the same product as used in the neutrik in line adaptors?. It only con is that it would have been nice if the winding had been identified to save the time to work out the correct phase connections!

If you need an audio transformer for coupling balanced/unbalanced signals, absolutely worth the price.
Although it's important to give it the right role: it works fine with limited voltage signals (pseudo-linear region) with all that goes from it

Good for low budget mic decoupling or for low energy line decoupling or to balance or unbalance line application.
Not bad for Balance/decoupling Synthtizer to go on a audio converter balanced line.

Does its job, at the price kinda only alternative, so its recommended

Have saved me a couple of times, installed on Neutrik NA-Housing. You know the rest.
