In Reply to: RE: Quick question: How do you filament bias a tube that does not have a filament? posted by Chip647 on October 16, 2014 at 08:02:13:
The current through the heater in combination with a separate bias resistor from heater to ground creates a node with a certain positive voltage. By connecting the cathode to this point, the cathode is raised to the same voltage.
