Hey, I gots a question for ya.  I have a walkman I carry on my belt,
and one day I managed to bang it pretty hard into a door frame.
After that I could clearly hear phasing problems in the highs, but
there is no head alignment screw on this box (an otherwise good
Sony Walkhominid).  Subsequently I noticed phasing errors on tapes
I ran thru the machine, and this phasing was still there when
I replaced the machine with a new one.  Is it possible for misaligned
heads to screw up the phasing on a tape even though it's a
playback-only machine?
