What is HV set at? If the regulator is glowing, there may be something awry with the grid bias circuit causing it to draw too much current. You can check by putting a current meter set to 0-1ma in the cathode circuit; with brightness at minimum you should have .8-1ma on the meter, and HV should be whatever the manual says. Usually around 23kv. If the regulator circuit checks out, roll 6BK4's you might have a bad one. There are more rugged versions on the streets, I have a 6BK4C from Tandy that looks like it has way heavier plate structure. But since I run most of my regs at minimum all the time, I never have this problem.
