Guys help me out here. I have trying to
post this for several days with no success. Let me know if you receive it or
repost it to the reflector if l can't.

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?
