From the description of the problem, it could easily be the line noise capacitor. It's connected directly across the AC line inside the power supply box. The definitive diagnosis is that when it goes, there is a really strong odor.
That's the understatement of the year, Michael :-). I would liken it to being under chemical-weapon attack.
When the line cap on one of my IIgs machines went up, I had to air out my office with a couple of fans for most of the day to avoid being gagged by the smell. Since this was mid-January in Vermont there were other considerations involved as well - starting by shoveling two feet of snow from the basement bulkhead hatch cover.
Whatever the oily substance in those caps is, I was unable to clean it off the power supply case pieces with anything at my disposal. Ended up tossing the entire supply.
