On multi-section cans I tend to check with the labeling of the can and the existant wiring to make sure of my work.
The first time I made that sort mistake I blew two lytics in a row because I could not find a way to get the chassis loose (the mounting nuts were recessed out of reach of a wrench), and a rubber AC mains line had disintegrated and shorted to one of the above chassis lytics.
The second time was a TV that I'd miss wired the replacements for the selenium doubler rectifiers on.....I was powering it up on a variac, went to have dinner, and started hearing a regular popping sound as the two sets of 5 22uF caps I had put in parallel to make up a replacement for each doubler cap started firing their guts out one by one.
