    On the right side of my NCS314 clocks case is a hole to a variable resistor labeled “adjust”. What does it do? I cant seem to find any info in the documentation.

    Hello Ric.

    This resistor, the Trimmer, adjusts the High Voltage supplied to the Tubes.
    Voltage in turn regulates the brightness of the Tubes.
    The voltage should be in range of ~175-190V for normal Tubes function.
