Calculation of choke value

[Kimly]

Hello, I destroyed recently a computer Power Supply , and opened it. Among heatsinks, dust, cables, silica seals, screws & o-ring washers, I've found something big and uncommon!
A choke!
I was looking for a choke, but I dont know what's it's value.

Can you help me to measure its maximum value without destroying it? It has no label on it...

thank you

Connect it in series with a resistor and feed it a sinewave signal.  Measure the output signal across the choke and the output across the resistor.  With these measurements you can calculate the value of the choke.
