Hi Warren,
                 Is there too much after touch and the jack is clacking
against the let off button rail?  Or the let off rail is loose.
The key slip has been pushed in, and the keys are knocking.  Loose nose
bolts.  Loose front rail.  Loose centre pinning can give the same effects.
An obscure fault.  Front pins knocking inside the mortice.  This is usually
accompanied by sluggish response. 
Is the piano well regulated?
Regards Roger
