An unbypassed equal-value series-resistance placed at each
cathode will equalize the tube currents and reduce the IMD, as well
as swamping the drive. The smartest engineering always uses one
part for multiple benefits whenever possible.
Consider that placement compared to a simple single shunt or
series resistance.
