I've recapped (240v analog board) a Macintosh Plus a year ago and everything was fine. Recently when I tried to boot it it blew its fuse. On further inspection I can see burned off pcb in C33.
I've attached photos of the carnage. Can I recover this? or is this analog board now dead?
Can you have a look at the bridge rectifier set (CR22 to CR25) for any shorted diode ? can see anything else that can blow the fuse and burn that capacitor on the neighborhood.

You should grab a dremel tool and clean out that carbon tracking below the capacitor. This will always remain conductive to some degree and start causing you problems.
