Easy enough to
open. I prefer using a rawhide mallet of the sort
used by jewelers. Just go round and round, tapping firmly on the
seam between the halves. Eventually, the thing just comes apart--

Yep, coincidentally enough I just got done doing approximately the same
thing you just described, and it came apart with no major trouble.
Inside there's a transformer connected to a small PCB with a fuse and a
pair of diodes. No capacitors, so I suspect there's not a great deal
that can go wrong with it.
Good to know. Now to dig out my cassettes... :)
