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!.


Not really. The audio is generally dervived from the sense antenna and
receiver. A failure of any part of the loop
antenna/reveiver/resolver/driver/mechanics/winring (in other words just
about anything) could produce those symptoms.
