The jack is not getting trapped, and we have verified correct balance rail bedding.

Try reducing aftertouch with a shallower keydip. Also, if a nearby hammer moves under a heavy blow, the balance rail may need re-bedding. Test by placing one's free hand on the keys at the balance rail about an octave distant from the offending notes. There should be no feeling of movement when the notes are struck. However, if this is a problem, it is unlikely to result in the one being discussed.

Other than that, these notes work just fine. This was something I had never seen before, so it took a few seconds longer than usual to figure out what was going wrong. Any ideas about what it was? Have a great weekend, Alan Eder Perhaps a somehat loose center pin in the whippen flange allowing it to flex enough that it catches on the neighboring knuckle/whippen? I think we are a product of all our experiences. Sanford I.
