[78-L] The infamous HMV crackle

[Doug Pomeroy]

The story I've heard more than once is that HMV added
some type of fibers to their shellac mix, and this causes the
crackle.  Why did they add it?  Ironically, IIRC, the idea
was that it would lower surface noise!  Anyway, this is
the anecdotal answer.
