I'm sorry for all the details, but this was a real gestalt for me.
In general, when a cassette squeals in the Nakamichi Dragon, the only
thing that helps is lubrication with D5. That was why I was so excited
by Shai's "discovery" as it provided a whole new perspective on
potential causes and cures.
Generally (and I'd love to hear Shai's answer with this specific tape),
placing the tape into a new shell has had no effect. That bypasses the
slipsheet question and the hub-to-shell friction.
So, thanks to you and others who mentioned slipsheets as that is
important. I had a cassette that would not play for a client and I was
able to make it play, and slipsheets were part of the issue--the ones
that came with the tape were all wavy and horrid. The other part was
minor layer-to-layer adhesion, but not enough to pull off mag coat.
I do not know what caused the adhesion, but I would not be surprised if
it were some exudate from the decaying slipsheets.
