I bet the temperature that softens the " insulating media" is
Maybe, but the termainl board certainly seems to melt very easily.
waaaaaaaaaaay lover than the temperature that melts
the terminal block. You
can use a SMD hot air station to blow air on the box and let the goop go
Oh, I managed to extract the intenrals from the box, But the box still
contained quite a bit of gunge (not a problem, I could scrape that out,
and I can also heat the box, being a metal can, to quite a high
temperature without problems) and of course there's similar potting
compound on the intenrals. I don't want to get those too hot for risk of
I can indentify the expected ocmponents in there -- (2 varistors that look
like disks with metal coating on the surfaces), the anti-sidetone
transformer ('induction coil'. call it what you like :-)), some
normal-looking resisotrrs, and a stack of 2 capacitors in a clip holder
thing. But with the gunge all overe them it's not easy to work on.
