Hi,

This afternoon, I have decided to restart my Apple ///, after some effort it works but the speaker make continuously a buzzing noise. Have you any idea of what could cause this ?

Thanks, matacao.

Stuck key possibly?

I have tested all keys and there is no problem, I think that I have an oscillation due to a faulty component in the sound circuit.
