Finally, after days, not hours, not one day, but days, my posts are finally appearing.

I have a GU-78B that has developed a grid short. I have determined the grid
short initiates about 2 minutes after power on and ends after about 5
minutes.
I have tried unsuccessfully to 'burn' the short by hooking up a 560?f
capacitor fed with 300vdc.
What other methods that can be tried to 'burn' this short?
Doug
