    Bose 501 - Diagnose and Repair

    I'm a beginner here so any advice or help would be much appreciated. I saved some 501s from going to the dump that were my father in laws.

    Bose 501 Series Info Please

    Were there any Bose 501 series made with rubber woofer surrounds? I have read conflicting information about this. I know some of the 901‘s had drivers with rubber surrounds.

    Bose 501. series I?
