Jack,  I don't think that "Instructions for Repairing, Adjusting
and Regulating Apollo Player Pianos" will help you in regulating your
1925 Apollo reproducing piano.  That tech piece is for the expression
pianos made by Melville Clark that play the Apollo X and QRS Automatic
Electric Rolls.

If what you have is a reproducing piano with the Amphion made action
that plays QRS Artecho and Apollo reproducing rolls, what you will
need is the Artecho shop chart.  A reprint was done by Vestal Press.
I don't know if it is available from anyone presently supplying
reprints, but I may have an extra copy.
