OK the reflector is working now. Before, my message
disappeared.
?
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?
