Why do the speakers buzz loudly? Almost unable to hear radio.

Speakers buzz loudly unable to hear radio, why?

THANKS otk03.

Took it apart - unable to locate any leaking or domed looking capacitors. Everything looks OK to me (?), though a bit dusty from 20+ years of use. Took some pics, not very tech savvy though, so... You'll notice the board looks a bit different, if that matters. Does anything stand out?

Any thoughts?

THANK YOU -- GREATLY appreciate your help.

Could be a multitude of reasons, but a failed electrolytic capacitor is maybe the likeliest. See https://therestartproject.org/wiki/Basic... for an indication of how to recognise it.
