The Sense wire is "matched" to the reciever, and there are many
different ways that the ferrite loops can be driven/sensed.

The best you could hope for would be that a later model of the same
brand might utilize similar antennas. You will have to talk to a
knowledgable avionics tech.

Thanks, I guessed there would be something different, there always
is-

It's only the pointer not working. Audio is ok so either sticking
pointer or driver circuit in the receiver. Hopefully repairable but
just wondered if a replacement would be economical or need the full
works!.
