Unstable regulation

[Aart in America Piano Services]

Hello Greg.

I have two customers with Young Chang grands. Both pianos have the same 
problem you are describing.
I will be regulating one of them next week, so I am very interested in 
information regarding this problem.
I'll let you know what I find out after the service call.

Thanks to All,

Aart
