I agree with the recommendation to replace the resistors as a matter of course. I have seen carbon 2W resistors in B+ dropping service and/or plate load resistors that went down in value so far that they charred and caught on fire. Replace dropping resistors with metal types of correct or slightly higher wattage rating and rest easy. When you consider the time you are putting into getting the radio to work correctly and safely, new resistors are a good policy.
