I have closed the box again, but I seem to remember
the socket did indeed
have a covering, presumably with components inside. Should I consider
replacing the whole socket, or is it possible to repair the individual
components inside? Assuming of course that the damage is not too great.
It is normal to replace the enbtire assembly, and it's quite likely that
a suitable replacement can be obtained. Of courde you might want to have
a go at repairing it. Whether this is possible depends on what has failed
and if you can get inside the module.
If it is a normal filter assembly, it will contain a bifilar-wound
inductor (which is almost impossible to obtain as a 'loose' component)
and 3 or more capacitors (which are avialable. There may be aschematic on
the can. If you get continuity from the liv/neutral pins to the tags to
whci hthe itnernal wires are connected, then the inductor is probably OK.
Most of the time if there are problems it's one of the capacitor that has
I suspect some of thse modules are filled with 'potting compound' (a mad
friend of mine clals this 'potting compost' :-)) which makes repairs
almost impossibel. Some DEC machines have a filter in a square metal can
about 6cm on a side on the back of the inptu conenctor, the lid is
soldered on. I think you van probably desodler the lid with a _large_
solderign iron and repari it. The type that looks like deep IEC socket
behidd the panel is probably not repariable.
