Does anyone know someone in the UK who might be able to fix mine?

It just makes a buzzing noise. It was a much loved gift, about 1986.

If it sounds fine through the headphone jack, there are detailed
procedures online for replacing a bad capacitor. Mine does the same,
but I just run it through an external speaker.

Thanks. Correct. A thousand thankyous. At risk of being cheeky I
don't suppose you have the URL?
