Dear List, Many of you know of the problem Yamaha had in the near past with their first generation of Ivorite. We have all seen the yellow keys staring out at us like coffee/nicotined stained teeth. What you may not know is that Yamaha readily wants to rectify the problem and get those yellow keys out of sight. But instead of sending us a set of keytops, Yamaha insists on replacing the entire set of keys. I am doing my first key replacement of this type for Yamaha in the next few weeks. The first step is to take careful measurements of the capstan center to the backcheck center and the capstan center to the back of key where it chops down to the keylifter felt. Question...Who has done this and what are the things to look out for. I imagine capstan and backcheck adjustment. Leveling and aligning keys. Dip........ Thanks in advance David ilvedson, RPT Pacifica, CA
