Hi Scott,
The following two sites seem to imply that amitriptyline is a somewhat weak NE alpha-2 antagonist:
http://www.gpcr.org/7tm/ligand/Seeman/a2adren1.html
http://www.preskorn.com/columns/9803.html (Table 2)
Clearly, amitriptyline's NE alpha-2 antagonism is too weak to produce an antidepressant effect by itself but perhaps, combined with amitriptyline's many other modes of action, it may slightly elevate amitriptyline's overall antidepressant effectiveness. Then again, maybe not.
