Today I was fighting a G07 chassis in a converted Gorf cocktail, when I suddenly had a stroke of "remembering" and fixed.
So - I make the last repair, and stick it in to make sure it's working now. I have a mirror on the floor so I can see the screen as the top of the cocktail is open. I hook everything up, power up, and have a perfect pic!
Well, I'd been fighting it for a good while and was very excited that what I tried (based on something I detailed here a little while back and i'm fixing to bump again) worked, and I lifted the cocktail top upright to show someone. This is when I find out that in my haste to test it, I forgot to put the retaining screws back in, and the powered chassis slid out of it's placeholders and shorted against the frame with a loud POP!

Of course, after replacing the blown fuse and suspect HOT, I can't get it to power up. B+ is at 160vdc. I've been over the chassis and can't find any bad parts. I grabbed another working chassis and used it to compare readings on all the various transistors, VR, HOT, IC, etc, and am getting identical readings.
So, what am I missing? I need this to work tomorrow...
