Anybody ever see the electrolytic on the heater supply leak?

Yeah, dumb ass, that's what happens when you put it in backwards.

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.

There's also the small electrolytic cap I put in backwards in the second BeePre. It was one of those computer electrolytics with the aluminum can over it.  There was a little pop, and the can shot off so hard that it deformed when it hit the equipment rack.

I got a Beveridge System II from Jim Lee of Nuts About Hi Fi, for cheap after a cap blew out of one of the amps and landed in his coffee cup. I still can't figure out how it got out of the chassis...
