All a brightener does is jack up the heater voltage fed to the CRT heaters. Makes the cathode hotter, and that scares up more electrons. For a while. It shouldn't matter if the CRT is 70 degrees or something else.
That said, maybe one of the regulars on this forum with a Beltron CRT restorer lives nearby. This machine can make a new emissive layer on the tired surface of the cathodes. Not without its risks...
