Ok, I replaced the capacitors (100uF 250V) and diodes (used the 1N4007s).I used the brake fluid on the case and the old paint is starting to peel off easily After that, I tested it. It chimed, but the screen remained dark. Also the cathode heater in the CRT was glowing quite strong.

Next, I wiggled around the anode cap, and now it won't chime anymore. It just makes a strange chirping noise. The heater still glows rather strongly, I forgot to mention that this is an International Analog Board version configured to 230V.

I followed The Dead Mac Scrolls, but the checks that Larry Pina suggests revealed nothing broken. Perhaps the problem lies in that broken anode clip?

Thanks
