Hi Ed, In addition to other posted suggestions, two thoughts come to mind. 1) Check for dried glue on the hammer rest rail felt. 2) If, perhaps, only sharps are clicking check to see that any overly long ones are not tapping against the nameboard (or it's equivalent) when the key returns. In general though, I favor Newton's suggestion in any trouble shooting situation. Isolate the problem by systematically isolating and ruling out the individual systems involved. In other words, "Divide And Conquer." Sounds tedious but it usually works well and you get to learn a lot in the process. Good Luck! Richard Wagner RPT
