I use several thin coats of clear lacquer and finish with RTV (silicone
rubber, for those who never heard of RTV--Room Temperature Vulcanizing).
This is very effective for driver transformers and chokes. I tried hot
glue, but it usually just reduced the level--it wouldn't get to the "core
of the issue."
As for "hearing" the offending frequency, Clancy covered that pretty
well. Two other possibilities. 1) In the home, have your customer be
your ears. 2) Invite the cute secretary from next door for a cup of
coffee and have her listen. Works for me. :-)
