Thanks Andrea, Yes you are right, it is in a tightly sealed casing and getting it open is probably going to be very destructive.
As per Rob and Paul's suggestion, I ended up removing it, since I was considering this open already. It running fine of course, but I will keep an eye out for a line filter which will fit in the steel housing. Thanks, Aaron. shadoooo via cctech writes: > Hello, > I don't have in mind the exact image of the filters of PDP11, but in some > case the filters are repairable in some way. > The hard problem of course is to dismount it. > Sometime these are stained iron foil boxes, filled with inductors and > capacitors, then some gel insulator, and finally soldered with SnPb. > Usually Rifa oil capacitors were used, which will explode after some years. > > If you have some mechanical ability, you could try to open the filter case, > desoldering it, or cutting on two edges, or removing bolts, etc. > > I successfully desoldered a filter of a Pro380, after it exploded. > It took a couple of good hours to do the work, but now has new capacitors > inside, and it seems like new. > > Andrea -- Aaron Jackson PhD Student, Computer Vision Laboratory, Uni of Nottingham http://aaronsplace.co.uk
