I always check the value of the resistors when recapping a radio or other vintage electronics. These have a strong tendancy to drift out of spec which typically is +/- 10% of the value shown on the schematic. Schematic should show the wattage too.
Once new caps and resistors are all verified then check the plate voltages against the schematics. If good move on to next tube, if bad check grid and cathode voltages…
