Marcel & Del,

   Del,  there was a Mason "A"  that had three 
extra one half size ribs in the high treble.  The 
last one that I replaced the board in I took out 
the small ribs and replaced them with standard 
size and number of ribs. It did not seem to make 
any difference.  It was a player and I think that it  
was  an  'A- 4'.  
 
    I have an A-3  #21158 in my shop now.  It has 
the standard number and size ribs. 
 
     Marcel,  If you don't have much experience in 
replacing  soundboards it may serve you well to 
practice on a less valuable piano.  Also let us know
witch "A"  this one is.  You can find this number in 
the left back of the plate.  

Regards to All,
Jack Wyatt
