www.esscoaircraft.com sells the maintenance manual for $65.  However,
if the unit is basically functioning, these ADF manuals will not let
you begin to solve this problem w/o an ADF signal generator and
dual-trace oscilloscope.

Check for cleanliness/integrity of antenna and all other connections.
And listen to the audio with the ADF set to "ANT" with
engine/avionics/strobes running to detect interference from any of
those systems.  That's where a good shop would start before hauling
the box to the bench.
