Do the following if you want to get your Amiga 2500 running again:
1. Remove 68000 processor.
2. Carefully unsolder and remove the IC socket.
3. Clean the area with 100% cotton pads and 99% Isopropyl Alcohol.
4. Solder in new IC socket (do not use a machined socket).
5. Plug in new 68000 processor (do not use old one).
Only use 99% Isopropyl Alcohol and 100% cotton pads (the kind women use to remove nail polish from their fingers) to clean the board. DO NOT USE ANYTHING ELSE!
After removing the 68000 chip and IC socket, and cleaning the board, use a 5X lighted magnifier to inspect the traces near the 68000 and kickstart chips. Make sure that none of them are broken or eaten away. You may have to use a multimeter to varify this.
Your Amiga 2500 should work after doing these things.
