The patient is an IBM 5154 display that has been recapped by someone who used no-name parts. The voltage ratings on the "new" post-rectification DC smoothing caps (the two big ones) seem suspiciously low for the rectified AC mains, and anyway one of them is quite bulged.
I'd like to replace the bad capacitors with better parts, so I visit https://caps.wiki/wiki/IBM_5154_EGA_Display for details. Helpfully, it says:
"There is a slight different list of capacitors for the 110V and the 220V versions of this display, so make sure you are looking at the correct list of caps."
The wiki page goes on to present exactly one list of capacitors.
Does anyone know the correct specifications for the electrolytic capacitors in a 5154 power supply that runs on 200-240VAC?
