If there is shielding around the vibrator make sure that it is grounded. Proud owner of a MGB I know gives me something to do in retirement. Started picking up engine noise in the radio on AM. My MG has a set of points! Connected a wire from the Bonnet(hood) to the frame problem solved. Me thinks you are picking up RF noise from the vibrator think spark gap transmitter. David
