In today’s video, I take on the challenge of repairing three different Amiga computers. One of them had audio issues, while the others required capacitor replacements.
Feel free to drop any suggestions, questions or comments below! If you’ve encountered similar problems with your Amiga or other retro computers, I’d love to hear your experiences. 😊

⚠️In this video, certain repair procedures involve handling internal power supply components, including high-capacity capacitors that may retain an electric charge. These operations can be hazardous for those without proper technical expertise and should not be replicated without specific training and appropriate safety measures. Do not attempt to repeat these actions without the supervision of an expert.
