Good advice for him Dave. Chances are, the
laminations probably were not coated with anything, or
maybe some shellac at best. I would highly recommend
the second procedure you mentioned. If he wanted to
be a purist about it, the tansformer could be removed
and submerged in a container of epoxy. Then a vaccum
is drawn on the container forcing ALL air out of the
laminations and windings. Then the vaccum is removed
and the epoxy fills in where the air used to be. It
would be a LOT of work, but the transformer probably
would not buzz again. But, I like your idea better.
