We have had some bobbling hammers on almost brand new Yamaha U5s
(and some older ones, too) here at University of Nevada, Reno. Check
your key dip. A couple of appropriately placed business cards under the
balance rail might fix things up real fast. Seems the key beds start to sag
just enough to give trouble soon as the piano drys out. Try it, you'll like
it.
