Smile XFMR Help?

First Post!!!! Hurrah!!!!
I am wanting to put one of these in a tube drive I made for creative purposes.
I want to know the ratio of the transformer and where to find a cheapo/medium priced candidate.

Any help identifying what's inside this puppy would be helpful.

It's just female XLR-XFMR-male TS jack.

Heres the spec link:


It says 250 ohm to 50K. So does that mean its a 1:200 ratio?????!!!!!!
That sure doesn't sound right
Thanks in advance.

That link doesn't work.
What you describe sounds like an inline microphone transformer designed to connect a low impedance balanced microphone to a high impedance unbalanced mic input.
If it's really 250 to 50K then the turns ratio will be approx 1:14 because the impedance ratio is the square of the turns ratio.
