Amiga 500 and Amiga 3000 capacitor replacement list

Hi, I've compiled a list of the capacitors that can be and sometimes should be replaced in both Amiga 500 and Amiga 3000, for my own needs, I'm sharing it here hoping that someone else might find it useful. All information is taken from the Service Manuals of the A500/A3000 respectively. All caps but only a few are "ELEC RAD" (Polarized Radial Aluminum Electrolytic Capacitors). The "ELEC AXL" (Polarized Axial Aluminum Electrolytic Capacitors) are on the A3000 daughterboard. All measurements are ca. in millimetres.

Please comment if you see anything wrong or have thoughts about this.
It's a mess trying to make straight columns in a forum as it do not make use of tabs or extra spaces.

Thank you . Very useful info.

[mrknight]

Thank you for this very useful piece of information! I have some random guru problems and I've started to suspect faulty electrolytic capacitor. This list will help me a lot, thanks!

[trixeo]

For some reason I am unable to edit my own posts.
Anyway, I've now successfully re-capped my A3000 following the list above. It works just fine! Some of the solder joints are a real pain to remove because they are soldered to a big ground area (which dispenses the heat very well) and my soldering iron is only 48W max which had a hard time melting the solder.
At least one of the caps had no "+" markings on the MB (C105: + is towards the CPU) so make sure and make sure again to get the polarity correct. Take a high res photo of the MB before you begin so you can check for polarity later. It's not that hard to find out which is ground though =)

Thanks and ordered!:cool:
