Your question was misleading because you asked for load
impedance.
My guess now is that you want to know what maximum anode
voltage and
current is for a 572-B. Max. voltage is 2750, and max.
current is 275 ma per tube.
If your plan is to run 4 tubes at the max. then the plate
load impedance would be
1388 ohms, but only if you are running 2750 volts @ 1100 ma.
Again, we are
also assuming AB-2 or B class.
