I recently acquired a Macintosh 512k and when cleaning the analog board, I noticed that battery had leaked down and ate off a couple legs from the line filter. It is labeled LF2 and it is connected to the AC plug port. I have removed it to see how much damage and I don't think I can fix the legs has they have corroded nearly flush. Is there anywhere that sells drop in replacements (has 4 prongs from the bottom) or a way to construct something similar that would work? Thanks!
