The screw on the upper part of the = "Jack/wippen" assembly is to tension for "lift". The lower screw, I've = not seen before! (might have something to do with the player thingee, = but I doubt it.These puppies are prone to the springs breaking! They = have at least 2 different spring diameters, as in Steinways, etc. The = fact that it's a player probably will exacerbate this problem! I have = many replacement "jack/wippen" assemblies, un-used at this point. With = the exception of the various adjustment screws being in different = locations and the weird spring that functions as a balancier, they = "regulate" the same as other grands. I hope that is of some help. Best Regards, Joe Garrett, R.P.T. Captain, Tool Police Squares R I ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
