Test #5

Doug Renwick
 

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?

When Y! gets goofy like that, I check the group on the web.

I made two posts last night and they have the correct time stamps of 12:18 and 12:28.? However, I went to bed a bit after 4:00 AM and they hadn't shown up here. As I use Charter as my ISP and Mercury Networks? For my mail and home page, the mail goes from Charter to Mercury via SMTP .? The post time stamp should be when I receive the post and it normally is, but not for those posts.
