Schematic not the best, but I think you would be OK with 10 watts ---- if there is nothing else dragging the rest of the voltage divider down. You will know better once you recap and recarb the set. If you have an analog 250 or 500 ma DCmilliampemer you can see just how much current this resistor is drawing by putting it in seriees with the hot resistor l (+ side to B+. ) I wouldn't expect to see more than 30-50 at most ma load from there. If there's more, something is wrong down the line. But do completely recap first at very least.
