In my case it turns out that these two resistors get hot anyway, so hiding them in a plastic tube was not the cause. The #11 was hidden in a plastic tube, but the #9 was hidden in some molded epoxy putty. I can see #11 getting quite warm as a 5 watt was what was originally called for in that position. #9 (9k) was originally to be a 1 watt and it gets equally warm, so I now have a 5 watt, 9k (as was original) in that location. Excuse my ignorance, but I'm still learning the theory and trying to understand if there is something else that could be causing #9 to get so warm that a 1 watt could not handle it.
Here are the resistors I made and then removed. #9 is actually a 13k made to look like a 9K. Below that photo are the 5watt resistors I temp installed. I plan to go back and make better connections on these two. Also the 1meg (brown, black, green) in the foreground is a fake too but it is fine. Only a 1/2 watt was required there. I like the idea of keeping the "look" of original, but I may just abandon that idea. This radio isn't going anywhere and only I will know what's underneath it.
