Silencing a humming transformer ( + ACDC adaptor that blew )
It does say it has "steel reinforcement" in it. To what extent it might
mess with a linear or swiching power supply, I couldn't guess. I would
use a different epoxy if in doubt.

Did anyone notice he was using JB Weld epoxy? I think that stuff has

I haven't used it yet. I have a few cheap rubbish ACDC adaptors most
or all of which make a noise. I broke one as described, but i'll try
to experiment on the others too.

it says it's an insulator.
I will reply to my post with links to pictures of the transformer.
