A common saga about that LP. -- Yes, some (often cheap) turntables can
play through that section without being thrown off, but nothing could
"play" that record as cut. The report I heard was that, due to a
cutting flaw in the first release, a turntable would have to reverse
direction for an instant in order to follow the record surface exactly.
Sorry, this doesn't make sense. How does a cutting lathe produce a
retrograde cut without itself reversing direction during the cut? As I
recall that LP, it was simply a case of an enormous recorded velocity
that was pretty well impossible to track with *any* cartridge, even
the super-compliant ones like the V15.
I saw a photomicrograph claiming to be of the cannon shot and there was
a clear "hook" in the groove wall. I know the cutter couldn't back-up
and didn't intend to cut a hook. Perhaps the impulse of the cannon shot
excited a resonance in the cutter or there was a weakness in the wall
at that spot and damage occurred at a later processing step that
resulted in the hook. (perhaps is was an enormous horn that was not
fully removed or the metal was bent during the horn removal attempt?)
