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.
