Radioroslyn;
I will check on the physical dimensions of the various wattage units. As long as a 10W will fit OK I may go with that. I am not seeing any indication that any severe short ever took place in this radio, so I think the OEM resistor just failed from long term heat and ageing issues. One 40uF electrolytic had been tacked into circuit many years ago and it does not appear that any other parts were replaced.
So far among the resistors I have checked I am seeing some that are out of tolerance in an increased value direction, but as a surprise, some appear right on the money. Many of the resistors in this set are 20% tolerance types.
