Cathode cap

A cathode resistor bypass cap in this circuit actually does nothing. Because there is a constant current going into the plate there will be a constant current coming out of the cathode. With a constant current flowing through the resistor there will be a constant voltage across the resistor, hence no AC signal, thus a cap will do nothing.
