This one’s a bit poorly, and is suffering from the usual dodgy capacitor problem. However, it’s in a lovely condition so be ashamed to let it die.
The little round silver things are the capacitors, and are directly soldered onto the circuit board, they are filled with fish oil, yes you heard it right, fish oil, and unfortunately this leaks all over the board when these go faulty.
So, its a case of removing each one individually with two soldering irons, and then replacing them with quality replacements. This is not a job for the fainthearted, as if you try to twist these capacitors off on this type of board, you’ll damage it because the traces just lift off straightaway. Be warned, these circuit boards are very delicate.
Pop back in a few days to see how it goes…
