I have a Lyon and Healy Troubadour III and, unfortunately, it still has its original levers (they are terrible!!!). The harp itself is in excellent condition, but I need to have all the old levers replaced with new more accurate ones. Does anyone know of a reliable repairman/woman willing to take on this kind of work? I don't have the time or skill to attempt it myself. I'm willing to drive a good way to get the work done.
