[78-L] Advance lacquers

[Michael Biel]

If Advance is the brand name of the blanks, I draw a blank on it.  There
was a device called an "advance ball" which was a device which rode on
the blank in front of the cutting stylus to allow the cutting head to
rise and fall with the rise and fall of the recording disc surface.
