Hey, you're not the first, and probably won't be the last. I've had a few caps barf on me over the years. Worse than that is the story I tell every few years about the really cool old Weston VOM in a beautiful limed oak box that I hooked up to a breadboarded 845 amp. I went outside the shop to paint something and looked back at the door, where the densest, most acrid brown smoke was just gushing out. The meter had a bunch of precision wirewound resistors that just couldn't take it. They were potted in that nasty old brown wax they used to use in old radio caps, and man, that stuff smokes when it burns. Shop smelled horrible for days after.
