Dwight.
That smells like one of the Rifa caps. Thick brown smoke.
Or was it one of the big electros?

I hate those filter caps. I had one go at the last Maker Faire ( no more
? ). I was trying out the Oregon trail when the nasty smoke started
pouring out. Luckily we had a drill handy to remove the rivets.

1/8" works OK, and will chuck in a Dremel.
If it were a damaged screw, rather than a rivet, I would use a
left-handed drill bit.
Which is pretty much what I ended up with. Surprised that this unit
looks in such good shape inside, I expected to see it already exploded.
Well time to get to work on it now and see if I can't get a working unit
out of it.
