From dead Mac to Happy Mac to sick Mac...

A few months ago my wife brought home her childhood Mac 512k, but she didn't know about RIFA caps and the Magic Smoke, so she booted it up and was playing a game for about five minutes before one of the RIFA caps blew.

Last month I ordered a bunch of capacitors and re-capped it. There was also corrosion damage from the battery which I cleaned up as best I could and replaced the corroded fuse clips. I connected my FloppyEmu, and for three days we enjoyed a Happy Mac running off the Floppy Emu.

Then it made an awful noise when she turned it on. (See next post for a video.) I opened up the Mac again and saw that the LF1 line filter right under the battery compartment had burned through one of the solder joints where there had been a lot of corrosion. I desoldered the line filter, cleaned that area up, resoldered it and added a bodge wire between the burned leg and the fuse. But it still makes the same noise when I turn it on.

I'm hoping for some guidance, or someone in/near Essex County NJ who can look at it.

Thanks,

Michael
