    Hickok TV-7D/U tests 71 and 72. A reading of 46 is the minimum recommended.
    The 12BY7A is a 9-pin miniature sharp cut-off pentode. It is used as a driver tube for the finals in radio transceivers, transmitters, audio amplifiers and as the final output tube in some very early tube type CB radios.
    Harman Kardon used six 12BY7A in their Citation II Audio Amplifier.
