About 21 years ago I had an old Crosley console that belonged to a buddy in my living room/work area that I had just finished up. Back then I didn't know of the importance of replacing capacitors. I just fixed what needed fixing to get it up and running. I was pretty proud, so I let it sit there and play for hours. At one point I decided to have a looksee and saw this goop dripping out of it and a puddle on the floor. but it was still playing. Immediately I cut it off and with the sound of the radio now gone, I could hear the sizzling from the power transformer. It had no fuse, not that it would have done any good anyway. Fuses are no guarantee that they will protect against this sort of thing. But as sure as you breathe, had I left the house with that radio running, I would have come home to my house burned down. There's only so much you can do.
