I had finally gotten my old Mac 512Ke together after a mildly successful floppy reapir, and after about 1 hour of use it started going crackle crackle and then a whole lot of DENSE NASTY SMELLING WHITE SMOKE... woah!  I pulled the plug immediately.

opened her up, and cant seem to find any burned capacitors on the ANALOG BOARD just from a quick look.  Have yet to check the logic board.    Which caps of analog and logic board are common suspects?  If there is a re-cap guide for compact Macs please point me to it (I cannot find it, but I read plenty references to it on this forum!)

Thanks!
