Edison cylinders rotated at about 185 r.p.m.  Originally
they played for only 2 minutes.  Later Edison introduced his
"Blue Amberol" records that played for 4 minutes.  (I think
the grooves were closer together.)

Not to change the subject (he said, changing the subject),
why are the golden ears not telling us how terrible `electrical
recording' (using microphones) is, and how the only way to
get an undistorted sound is to use a diaphragm directly
connected to the cutting stylus, as was done throughout the
first fifty years of the recording industry?  B-)
