   In the 1920s and 1930s many "audiophiles" did indeed run their amplifiers   
   and radio receivers on lead-acid batteries as it was believed to be   
   impossible to make mains operated equipment totally hum-free (of course   
   those who lived in rural areas often didn't have the choice).   
      
   The original Western Electric cinema sound equipment used lead-acid   
   batteries for the exciter lamp and the early stages of the amplifier. Dual   
   batteries were provided so that one set could be on charge whilst the other   
   was in use.
