    I've bought an old vintage car radio from 1960's and the guy I bought it from said that he accedently put + on - and - on +, and now the sound that comes out is noice togather with the normal sound.
    Does anyone know what the problem mightbe and what component I'll have to change?

    Hello,

    What kind of noise do you experience?
    Is the noise related to the speed of the motor?

    If you can look inside look for blown electrolytic capacitors. The newer ones are much smaller and more reliable, but I have no idea how enthusiasts feel about using modern components to replace old ones.

    Hm,it sparks, and it's not related to the speed of the motor since I've tried it on my 12v car battery that wasn't connected to anything else but the radio.


    I've nothing against replacing old parts with new ones. I'll have a look.
