You can't measure (or observe) the one on the other side?


While not quite symmetric, the other channels crossovers
coil is burnt worse than the one i am looking at now. So, no
chance for a good part measurement.


How badly burnt?

I've seen some pretty ugly messes based on an heavy-gauge wire choke that
was still OK.

For openers, unless they were burnt open or fused, I'd measure both coils
and see if they still measure the same.

On a really bad day, wind up a coil of the same gauge wire and same number
of turns in the same form factor and measure it.
