The best bet in tuning an old player is to tell the customer that he or she should have the player mechanism restored and re-tubed, other wise they are wasting their money on tuning if the player isn't working properly. An in tune player that isn't tracking right, and has leaking valves and pneumatics, and bellows that leak, will still sound bad. Before you jump into rebuilding players, you better do some homework, because there were hundreds of different makes in the early 20s and 30s, and each one is a little different. It is definitely a field of its own, and takes years to master. Roy Czekay </HTML>
