    2. Filament: 0 – 6.3 VDC, 2.5 A. Voltage and current meter provided.
    3. Plante: 22, 45, 67, 90 and 135 VDC, 60 mA maximum. Current meter provided.
    4. Grids: 3 independent voltages: -4.5, -9 and -22 VDC, 20 mA each. Voltages can be fixed or adjustable.
    5. All adjustments use multiple turn potentiometers.
    6. Fan cooling.
