I'm working on a 41-280. The power transformer has a little bit of what looks like wax at the edge of the hole the wires go in. I'm pretty sure at least one of the electrolytic caps was replaced at some time in the past, maybe all three. My question is about whether the wax indicates a past overheating problem that was corrected by replacing a 'lytic or whether the problem is something I need to worry about now. I replaced all the 'lytics last week, by the way.

After the radio has been on a while, maybe an hour, the transformer is warmer to the touch than I would have expected, not hot enough to burn, and not nearly as hot as the 84 and 41 tubes, but surprisingly warm.

How hot should these transformers get when they are operating normally? The metal cage around the transformer was removed and lost by someone before I got it.
