The ambient temperature underneath a typical 5 or 6-tube chassis can rise over 100 degrees in that enclosed, poorly ventilated space - conducted heat from the tubes and large power resistors, and the power transformer.

The beeswax may not melt, but over time it will soften and creep and slough off the coil. I've seen many coil forms with all the impregnating wax globbed up at one end (lowest point) of the form from this.

Just my observations.
