old US Telephone hybrid ('Network' block)

Maybe, but the termainl board certainly seems to melt very easily. 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 damaging them. 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. -tony
