>Hi Theodore,
                The fabric softener sounds like a good idea. I'll try it on
a section on the next one. The steam was an easy winner for shop work.
 I routinely steam, wip cloth with a wet cloth and iron on these units,
then spray with teflon powder, it makes a big difference. The drop button
leather also tends to be too stiff in these models adding to the noise. I'm
not so sure if the felt and leather products are the real problem, or, the
glue wicking into the material. 
  The over view of these actions is that there is an accumulation of many
things. that add to the clatter. If you have a day and a half, start with
carefully bedding the frame, work your way systematically through the hard
felt problems. shrink centre pin bushings as required. Tail hammers
correctly and remove some mass from the sides of the hammers. 
  After careful regulation they can feel and respond very much like a Yamaha.
In fact after doing this work we find that, consumer choice is about 50-50.
There is a bass warmth thats attainable, that is not normally found on the
budget pianos. The  basic scale design and balance of these units is very
acceptable. With the value added work that we do, we increase the selling
price accordingly.
