Arghhh!! Not again.  This discussion seems to come up every six months
like clockwork.  Maybe we can get Spaf to add it to the list of
frequently asked questions in net.announce.newusers.

One more time...  The ghost you hear is not caused by tape print
through.  It is caused by a deformation of the vinyl.  Why?
1. You can find the problem in many all-digital and brand new
   recordings.
2. The problem is not observed on Compact Disc versions of these LPs.
3. The ghost appears exactly one turntable revolution before the music
   begins.

If you want more reading on the subject, perhaps you could find
someone who archives net.audio to mail you the 2 zillion previous
articles on this topic.  1/2 :-).
