Are you referring to the GA1E? They were the ones made in Indonesia.  
Yamaha's first. I have had many replaced. Including the disklavier models. The  issue 
is at B2 to B3. I have seen A#2 at pitch, and B2 90 cents flat in the  
winter. Humidity was 25%. Then in the summer B2 was 60 cents sharp. Humidity was  70 
%.
Yamaha says they do not want these pianos out there. They replaced them  with 
the new GB1.
