Hello MMD'rs,  Can any one recommend a resource (a book or better still
something on-line) that would give me a good overall understanding of
how to rebuild / repair / adjust a piano action?  Perhaps something
similar to Art Reblitz's excellent book on the player action, "Player
Piano: Servicing and Rebuilding".

Also, where should I purchase parts for the piano action?  I don't know
if PPCo is a good resource for these parts any more or not.  Is there a
source that will sell in small quantities and not have to prove that you
are a certified piano technician before they will do business with you?

Thanks in advance,
