[pianotech] What's causing this vibration?

[jere fryett]

I had a similar problem recently, but it wasn't a vibration problem.  This was on a 1970 Wurlitzer spinet and when you played D4 and F4 together it produced a kind of hoarse sound.  Hard to explain.  Each note played by itself did not give the sound, only when played together.  I don't even know where to begin on this one.  Any ideas?

Coins in a piggy bank or a change dish can make a real hissing tin foil sound.
