This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment Had the same "sound" in a Wurlitzer upright ... buzzed mostly when I = played A4. Turned out to be the lock for the lid ... only made the noise = when it was opened for tuning ... taped it while tuning. Point: Are you = sure it's the plate? I read about a tuner that went nuts looking for an = out-of-tune resonant buzz in a piano ... finally found it was a loose = piece of glass in a leaded glass window near the piano!

I have a client with an M1F = from Yamaha. It's only a few years old but already, Yamaha has = discontinued the line. It's a 43 " upright and it has one of those = crazy lids that lift up like a grand piano. Anyway, I noticed that after I strike a key anywhere in the treble, I = get a metalic sound that is not in tune with the note struck. It was = obvious to me that the sound I was hearing was the iron plate vibrating = for a short time after the note was struck. However, as I mentioned, it = was a terrible out-of-tune noise. It's not extremely obvious but it is = loud enough that it drives the owner crazy. The plate screws are all = tight, as is every other screw I could find. I wonder if this was why this series was discontinued. Anyone ever = run into a similar problem?
