    Help!?
    
     I have a new customer who says her previous tech told her that her 10-20 year old Young Chang upright has "expanding action brackets".....This sounds vaguely familiar like I've read about it before but I am currently clueless!???....What does it mean?...How can I get parts and how many hours of a job is it??...

      Jonny,
          This is a well documented problem for Y.C.although I have not seen this on verticals.
          Call Y.C. and ask for tech support---- only  after you evaluate the action and have the model and serial # on hand.
          In the grand actions the symptoms can include blocking hammers , letoff dowels turned down to the point of falling off .
      ,drop screws rubbing on the pinblock.etc. 
          I would sample regulate  a few notes in each section to test.
          If the usual adjustments don't fall into place ,I would call Y.C. for advice.
          They will give you action spread dimensions and some direction for replacing the brackets if indeed they are problematic.
           A healthy dose of skepticism as it relates to the other techs diagnosis is in order here in my opinion.
           Why didn't the tech pursue the repair if the diagnosis was correct?
          Maybe there were extenuating circumstances but why not fix the problem?
           
          Best of luck,
