untunable [Young Chang] G-150

[Scott Nelson]

As I recall, the serial #'s with that particular problem ran from about G091500 to G0103999. I believe Phil Glenn told me that they went back to brass at 104000, but with the existing profile. The originals can be retrofitted with the brass, but the one time I did it, it was very tough to get the existing inserts out. Phil told me, however, that he had not noticed any particular problem with the removal. I don't know if Young Chang would still have the replacement inserts, or what difficulties you would have in obtaining them.
   
  I have not experienced any particular string breakage problem with these-at least none that I wouldn't attribute to the rock-hard and unshaped hammers frequently encountered or excessively heavy playing.
   
  Hope this is helpful.

  Yes, as I recall there are two zinc string rests in some pianos.  One under the capo, and one as the counter bearing.  They are unpainted metal, but are not as shiny as the usual chrome rear aliquot bars.

  What do you do if you find one of these? Also, can these, or any other insert used by YC, contribute to string breakage? I am about to restring a model 213, serial G099xxx, which eats treble wire. I don't find it hard to tune, so it might be later than the zinc. 
   
  The tensions are very reasonable. I have told the client that it is the rock-hard, unvoiced Renner hammers (which we will also be replacing) powered by her heavy hands that are the culprit, but I don't want to leave any stone unturned. 
   
  Thanks,
