The 425 network was not field rpeairiable, and I can
see why. After
bending up the tabs, I slid off the can to reveal the components in a
particularlly evil potting compound. It's not hard, it's sticky, I can be
scraped off (but I spent good quarter of an hour clenaing a screwdriver
after this). It will soften with heat (in fact a hot air paint stripper
gun wil lget it to drip off, but I was gettign the thing so hot that the
plastic terminal board was softening too). No solvent I have tried will
remove it.
The BSP docuemtns simply call it an 'insulating medium' which is not much
help :-).
Has anyone ever repaired such a Network block and knows how to shift this
stuff?
Here's a replacement for $20:
