By then, many were made in Japan, and Japanese AA5 tubes were also made in Japan used by American radio and TV manufacturers. After that, solid state radios, many using a high voltage audio output resistor and thus were also "hot chassis", became the preferred technology. CL |

Many tubes were marked with the month and year they were made and that could give you an idea of how old the radio is. |
