    I'm trying to calculate load lines for the tube prior to the phase inverter in the 5E8-A schematic. The schematic shows 1.5V at the cathode junction.

    There is DC flowing from ground through the cathode resistor but am I right in thinking that there is no DC flowing from ground through the presence pot because of the capacitor?

    Thanks! twin_5e8-a_schem.png
